Error creating Queues in RabbitMQ - erlang
I have an environment in our company which hosts RabbitMQ 3.6.1 and Erlang 19.3. When i tried to create a queue by using RabbitMQ Management UI, I am getting the below error. I can create Exchanges and VHosts ok. It is only when I am trying to create Queues that I am getting the error. I tried to write a utility to create queues using the HTTP api but even that fails.
Upon some more researching I stumbled upon this article https://groups.google.com/d/msg/rabbitmq-users/pa1UtLbbvOE/3OlgKgMBAgAJ which says Erlang 19 is not compatible with RabbitMQ 3.6.3 and lower. Can someone confirm my findings please?
The error I am getting is
Got response code 500 with body {"error":"Internal Server Error","reason":"{error,\n {exit,\n {{function_clause,\n [{rabbit_queue_location_validator,module,\n [\"random\"],\n [{file,\"src/rabbit_queue_location_validator.erl\"},\n {line,50}]},\n {rabbit_queue_location_validator,validate_strategy,1,\n [{file,\"src/rabbit_queue_location_validator.erl\"},\n {line,38}]},\n {rabbit_queue_master_location_misc,get_location_mod_by_config,\n 1,\n [{file,\"src/rabbit_queue_master_location_misc.erl\"},\n {line,88}]},\n {rabbit_queue_master_location_misc,get_location,1,\n [{file,\"src/rabbit_queue_master_location_misc.erl\"},\n {line,51}]},\n {rabbit_amqqueue,declare,6,\n [{file,\"src/rabbit_amqqueue.erl\"},{line,300}]},\n {rabbit_channel,handle_method,3,\n [{file,\"src/rabbit_channel.erl\"},{line,1331}]},\n {rabbit_channel,handle_cast,2,\n [{file,\"src/rabbit_channel.erl\"},{line,455}]},\n {gen_server2,handle_msg,2,\n [{file,\"src/gen_server2.erl\"},{line,1049}]}]},\n {gen_server,call,\n [<0.27627.105>,\n {call,\n {'queue.declare',0,<<\"Test\">>,false,true,false,false,false,\n []},\n none,<0.15368.105>},\n infinity]}},\n [{gen_server,call,3,[{file,\"gen_server.erl\"},{line,212}]},\n {rabbit_mgmt_util,'-amqp_request/5-fun-0-',4,\n [{file,\"src/rabbit_mgmt_util.erl\"},{line,579}]},\n {rabbit_mgmt_util,with_channel,5,\n [{file,\"src/rabbit_mgmt_util.erl\"},{line,598}]},\n {rabbit_mgmt_util,http_to_amqp,5,\n [{file,\"src/rabbit_mgmt_util.erl\"},{line,526}]},\n {webmachine_resource,resource_call,3,\n [{file,\"src/webmachine_resource.erl\"},{line,186}]},\n {webmachine_resource,do,3,\n [{file,\"src/webmachine_resource.erl\"},{line,142}]},\n {webmachine_decision_core,resource_call,1,\n [{file,\"src/webmachine_decision_core.erl\"},{line,48}]},\n {webmachine_decision_core,accept_helper,1,\n [{file,\"src/webmachine_decision_core.erl\"},{line,612}]}]}}\n"}
The RabbitMQ team monitors this mailing list and only sometimes answers questions on stackoverflow.
In your case, the error is happening here. Did you create a queue-master-locator policy with the value of random? If so, I recommend clearing the policy to see if that resolves the issue.
I also recommend upgrading to the latest version (3.6.12). The version you are using is very old.
Thanks to #Luke Bakken for pointing me to the RabbitMQ Mailing list.
I managed to fix the problem by changing the configuration of queue master location strategy to <<"random">>

The Dataflow appears to be stuck
Got the following message: The Dataflow appears to be stuck. Please reach out to the Dataflow team at http://stackoverflow.com/questions/tagged/google-cloud-dataflow. I realized there were other questions regarding the same error message, but the context seemed different for each and the message rather generic, so I'm posting again. Job ID: 2017-09-25_09_27_25-5047889078463721675 Please assist. Thanks. EDIT: Problem seems to have disappeared (at least for now) after updating to Apache Beam SDK for Python 2.1.1 from 2.0.0.
A common cause of stuckness in Dataflow pipelines is an inability to start the workers. If you look at the Stackdriver Logs (view Logs in the UI, and click the link to go to Stackdriver) you should be able to view the worker_startup logs. Any problems here can indicate failures to start workers, which would cause the job to be stuck.
SonarQube Service Starts, Runs and then Stops?
I have a Windows 2012 R2 server and I managed to install the SonarQube 5.4 server as a Windows Service. I also set up a user so the service can actually start without the infamous "It started then stopped" error a lot of people seem to get. Before installing the server as a windows service, I checked that it worked using StartSonar.bat and it did work just fine, so I was confident when I made it into a service. But when I try to access http://localhost:9000 there is nothing there, and it appears that shortly after starting the service it stops without any message at all. I can't tell if this is because I try to access the site (which gives me ERR_EMPTY_RESPONSEin Google Chrome) or if it just closes down after a short while. Anyone got any insight?
I'm a beginner. I came across the same issue and fixed it. Ensure that the database is running. My log file (located at sonarqube_home_dir/logs/sonar.log) included the following statement. Caused by: org.h2.jdbc.JdbcSQLException: Wrong user name or password [28000-176] Since I'm using the default database, I commented below lines #sonar.jdbc.username=*** #sonar.jdbc.password=*** at sonarqube_home_dir/conf/sonar.properties.
This must happen due to many reasons like connection problems, permission problems so First, you have to see the logs. /sonarqube-7.6/logs$ tailf sonar.log. then you can find the reason. Once I had the same problem so I did like that. my error is something Directory does not exist: lib/jdbc/mysql org.sonar.process.MessageException: Directory does not exist: lib/jdbc/mysql reason is I uninstall MySQL and remove all folders name contains "MySQL".
just check whether port 9001 already in used, stop it if already in used.
wso2 esb console localization
I'd like to translate the management console to localized language. I've try to follow the instructions from http://wso2.com/library/knowledge-base/2011/11/playing-around-carbon-product-themes/ as a starting point, cause I think that should be in the same theory. But this didn't work, and cause an exception when entering the site. I see the document is pretty old (2011), is this not work anymore? or the procedure has been changed? Edit: sorry, forgot to mention, I'm using WSO2 ESB 4.8.1.
Yes as you have mentioned, above link is outdated. However, the concept is same in new versions as well. Keeping an extracted jar file in the plugins directory will no longer work since we have disabled that along the way as a security fix. Herewith I have given [1]. the latest documentation of "Customizing the Management Console" of the WSO2 Enterprise Service Bus. You can use it as a starting point. If you need further help regarding this issue, please let me know. Thanks, Upul [1]. https://docs.wso2.com/display/ESB481/Customizing+the+Management+Console
TFS 2010 Build: Sporadic failure in the process
We have a situation where our builds have stopped executing in a stable manner. At a rate of about one every three we receive either TF215096 or TF215097 errors & the Build fails. If we then restart the Build controller, it works again - until next time. The errors we get are: TF215096: An error occurred while connecting to controller vstfs:///Build/Controller/1: There was no endpoint listening at ht*p://XXXX that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. TF215096: An error occurred while connecting to controller XXX - Controller: Could not connect to ht*p://XXX. TCP error code 10061: No connection could be made because the target machine actively refused it 192.168.XXX.XXX:XXX. TF215097: An error occurred while initializing a build for build definition \XXX: Team Foundation services are not available from server ht*p://XXX. Technical information (for administrator): The underlying connection was closed: A connection that was expected to be kept alive was closed by the server. TF215097: An error occurred while initializing a build for build definition \YYY: An error occurred while receiving the HTTP response to ht*p://XXX. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details. Server logs provide with little info, at least we 've found nothing that helps us resolve the situation. Various searches in the Net were also not productive. Does anybody had these/similar issues? Any ideas on how/where to look for a resolution? Thank you very much in advance for any input!
Yeah it does sound like you have some connectivity issues. You can try enabling SOAP tracing on both the build machine and the server (if possible) to see if there is any error. If it still does not give you any new information, contact Microsoft by filing a Connect Bug to get help.
I am not sure if it will help you but I have ran into similar issues with build agents and ended up just deleting and re-creating the agent. You may try deleting your controller/agent and adding it back in. A brute-force solution but a good starting point. If that doesn't resolve the issue at least you can eliminate the controller/agent as the issue and take a look at network/server related issues.
Today is a happy day, since we managed to get to the bottom of the matter. Sorry #Duat that I'm taking away the 'answer' checkmark - but it turned out that the problem was quite different from what you (and anybody else) has predicted. In my last update I was about to forward the matter to MS, when we realized that our Firewall was misbehaving in the name resolution. So we assumed this was the culprit & awaited for this to resolve. After this was resolved, we STILL had the same issues and we went again re-examining the situation. We isolated the problem within our Build Process, more specific with a custom code activity included in our build solution. I had implemented a code activity that would kick in at the final steps of every build. This activity was about gathering BuildDetails about the running build & add them as a new line in a 'BuildLog.xls'. Implementation made use of Microsoft.Office.Interop.Excel.This excel sheet resides in another server (NOT on the Servers where the controller/agents reside). During development of this activity I was faced with issues like this, but after I was done no instances of EXCEL were left hanging. So I thought this was done & dealt with. With try & error, we observed that when this activity wouldn't ran, no problems would occur. With this activity running, the very first build after a build-controller reset would succeed, any next build had a certain chance to fail. Once any build failed, no other would succeed until another build-controller reset. I have only a general understanding of what the problem was (Excel-call is DCOM, TFS services are WCF : How on earth would they interfere?! Why would this sometimes succeed and sometimes fail?! ). The provided diagnostics were no help either, in fact they mislead us into a loop that continued for months. If I ever find the time, I 'd like to cleanly reproduce the error & make a Server Fault question out of it... After removal of this activity it works! I now searched in SO & found this, where J.Saunders comments: "In general, you should never use Office Interop from a server environment". It's ironic that once you get to the bottom of any difficult issue, the whole universe seems to have known about it except you...
Rabbitmq erlang client build failed due to file paths problems?
I have been able to build rabbitmq server on ubuntu linux. It came already prepackaged and on making, it is able to start as a service. When i got the client source, i failed to make because it appeared like it needed a folder called ./deps/rabbitmq-server. Analysing the code, i find that the author of the client was accessing the same header files as are found in the server, using include_lib("path to rabbit.hrl e.t.c") in his header file called "amqp_client.hrl". I then decided to add rabbitmq_server in the lib dir of erlang so as its paths are automatically added on start up of the vm. But still this didnot help. There is also another folder which the client references called "rabbit_common" for an include folder he assumes would contain all the .hrl files there. Please assist me in building both the client and server on my ubuntu server, for testing. Also, if anyone has used RabbitMQ server for IMs, please provide some benchmarks and/or your findings on its throughput, speed and number of users. How can it be compared to ejabberd?. How can one create AJAX/Jquery/Javascript clients for Web functionality? thanks
I hope you had made some progress as far as RabbitMQ and ejabberd are concerned. Below is a link to an interesting discussion that might be of help. http://old.nabble.com/AMPQ-vs-XMPP-and-RabbitMQ-vs-ejabberd-td17587109.html
