How can i detect this exception when i start my application:
org.springframework.amqp.AmqpConnectException: java.net.ConnectException: Connection timed out: connect
The project is configured in the Spring way (http://projects.spring.io/spring-amqp/) and I can see the errors in the logs, but I can't detect it in my java Classes.
Consumer raised exception, processing can restart if the connection factory supports it. Exception summary: org.springframework.amqp.AmqpConnectException: java.net.ConnectException: Connection timed out: connect

This can happen for example when you have no access to the AMQP port.
Thank you!
There is currently no event emitted when this error occurs (I have created a JIRA issue to add one.
In the meantime, since the the connection is shared, you could call createConnection() on the connection factory from your own code from time to time, to check the connection state.
Or, you could hook into the logging subsystem to capture the WARN log, as I described in this answer.

I have tried changing the port the database (Which I think it’s what it’s trying to connect to) from port 5432 to 5488 but I get the same error. I have read other stack-overflow posts on this error message but they haven’t worked either.
I have also tried to speak with the company that made this project but as is understandable since this is an open source project of theirs from which they make no money it is not in their priorities to fix this issue.
So hopefully one of the brilliant minds roaming this site can help me out.
If you want more info on what the repo is for
Bringing data from wearables and medical IoT devices to FHIR solutions
I see container_name: timescaledb in docker-compose file. Hence host will be timescaledb and default port 5432 if you are trying to connect from another container in same network
I have a Ubuntu master machine and windows 10 slave machine
I need to connect slave machine(windows machine) from master machine(ubuntu) using SSH Connection

In the key configuration you should put the private key not the public key
And in the slave machine you don't need to install Jenkins
Starting today some of our slaves in our Jenkins master started to disconnect with the following error:

I've read about this issue and tried to figure out what caused it. I have around 85% or the rest of my windows slaves still connected and running.
Slaves : Windows server 2012R2
Connected with JNLP protocol
Jenkins version : 1.609.3
If more information is needed let me know and I'll supply it.
This usually means that there was a network error, such as a TCP timeout. I would start by placing a sniffer (wireshark) on the connection to see if you can see any problems. If there is a TCP error, you should be able to see it. Also, you can check your router logs, if this is applicable. If wireless is involved anywhere, that is another source for these kind of errors.

I just started using Jenkins and I'm seeing an issue where my slave services is crashing while running a job(the job executes an .exe program). The error I'm seeing is as follows -

Any help or insight on why this is happening would be great!
Eric
I am using Jenkins. Go the particular node,
Click on Configuration then in JVM options enter -Xms512m -Xmx1024m
That will increase the heap size.
I have been using flume for a while now, I have got agent and collector running on same machine.
Configuration
agent: exec("/usr/bin/tail -n +0 -F /path/to/file") | agentE2ESink("hostname", 35855)
collector: collectorSource(35855) | collector(10000) { collectorSink("/hdfs/path/to/sink","name") }
Facing issues in the agent node:
2012-06-04 19:13:33,625 [naive file wal consumer-27] INFO debug.InsistentOpenDecorator: open attempt 0 failed, backoff (1000ms): Failed to open thrift event sink to hostname:35855 : java.net.ConnectException: Connection refused

and then empty ACKs will be sent continuously

I dont understand why the connection is refused. Are there any system level changes that needs to be done ?
Note: the collector is listening to the port but agent is unable to send data through the 35855 port.
Can anyone help me with this problem.
Thanks
If you are running both the agent and the collector on the same box, you should be using localhost as the address.
agentE2ESink("localhost", 35855)
