Jira behind Apache sometimes slow

Aleks

Our Jira is running behind a apache (reverse proxy). Sometimes Jira is running very slow. Apache is throwing the following errors.

Does anyone know how to fix this?

[Tue Jan 08 15:36:56.160575 2019] [proxy_http:error] [pid 3180:tid 1052] (OS 10060)A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond....

It means what it says - the Jira server is not responding to requests from the proxy.

You'll need to have a look at the Jira server to see why it is slow and non-responsive.

well, there are several log-lines. after a restart of the jira service today, everything worked well.

There is something about a memory leak in the jirasoftware.log and GC overhead limit exceeded in atlassian.jira.log.

Am I right?

Yes, the GC error is probably the culprit, as Jira will run slow before doing it and then die as it happens.

The important log here is the atlassian-jira.log, but a GC error is serious, it means there is something wrong with the memory settings, or you don't have the resources or run the system, or there is a memory leak, or, or, or...

You'll need to investigate and monitor this for further occurrences, and probably tune it - start at https://confluence.atlassian.com/enterprise/garbage-collection-gc-tuning-guide-461504616.html

Thank you very much!

As a short term solution I increased the Heap Memory.

I had also a closer look at Troubleshooting and support tools.

The performance issues could be caused by some mail issues.

OutOfMemory due to Large Mailbox Processing
OutOfMemory due to Mail Loop
OutOfMemory due to Custom Services
JIRA applications crash due to OutOfMemoryError Java heap space
Mail Queue Must Be Flushed Manually due to OutOfMemoryError

The strange thing is, we don't have any Custom Services and no mail handler (at least not for jira). we are using jira service desk and the Create Issue from Mail is handled by Jira Service Desk.
