I have deployed my Rails application on server.
It is working fine, but it crashed on sign_up page and server will be stop.
I Checked my mongrel.log file, it give the following error.
libgomp: Thread creation failed: Cannot allocate memory
How can I resolved this error?
Thanks.
Guess what. Your server is OOM.

I'm using Amazon instance to to run my Ubuntu server, i depyoed new feature and did
rake assets:precompile RAILS_ENV=staging
but i got error while pre-compiling
Allocation failed - process out of memory precompile
I found out that my CUP usage was 100%. I exit that proecess. But now i'm not able to SSH in to my server. The instance on AWS is running state.
it says ssh_exchange_identification: read: Connection reset by peer
Ok, It turned out I was running multiple process like sidekiq, rails console and my error logs in other terminal. So it drained a lot of RAM memory that time.This is why the server stopped responding.
I restated the Instance so i was able to log in to the SSH and then only ran precompaile and it worked. Still the memory usage was around 95% but other processes were close that time,so the precompailatoin ran successfully.
I'm using this server just as staging/testing server before production so there is no point of increasing memory(As of now). SO the above solution worked for me. Hope this might come in hand for you guys.
I have a Rails 4.2 app running on Heroku. Occasionally there is an issue that causes most incoming requests to get a server error. For example, there could be a memory leak or a max database connection issue. How can I setup a script or service to automatically restart the server when it detects errors?
I think this service could ping the app every few minutes and if it detects an error, it should confirm there's really a problem and then run heroku restart. How could this be set up?
After Googling this topic, I came across Neptune.io, which seems to provide a useful service for this task.
I have a rails app on heroku that users log in to. I periodically get this exception:
UserSessionsController#
(ActiveRecord::StatementInvalid)

What's a likely cause of this? I'd appreciate any help.
Assuming you saw this recently, this is due to a recent bit of high-priority maintenance work to enable continuous backups on shared databases -- involving a server restart. You shouldn't worry about this error, provided it does not reproduce. I don't think that's very likely, so happy hacking!
I had this error happen to me. My Application server had an open connection to the database. In my SSH terminal I added an ipaddress to the ph_hba.conf file and restarted the postgreSQL server.
That is when this error showed up. I refreshed my web page one time and the error was gone.
This probably means that something sent the server process a SIGTERM signal. This could happen is if the postmaster gets a SIGINT from something. However, if you are able to reconnect that's not the case, because the postmaster would disallow new connections.
You're probably having a clash of some kind in your application. Enable query logging and check for something unusual.
This error may also appear, if you run a test suite which utilizes a database connection (PSQL in this case) and the test is still running (asynchronously).
A tear down hook may terminate the connection when the test is still running and this ends up in this error message.
Sometime i will encounter this error after multiple access of my web application
I am using Sun Application Server Platform Edition 8.2
What is the reason for encountering this error and how to resolve it.
File system permissions issue perhaps. Need more information for a better answer.
