Jira Crashed. Giving java.lang.OutOfMemoryError: Java heap space

Tayyab Bashir

Hi,
My JIRA server crashed and in the logs its continuously giving Java Heap space and Out of memory errors.

I am also using a third party plugin "Bug watcher".
There are many errors from that aswell, But before that JVM ran out of space.

Hey Muhammad,

Please find following articles

This is because of Bug Watcher Notifications plugin

https://confluence.atlassian.com/display/JIRAKB/Unable+to+obtain+a+connection+from+the+underlying+connection+pool

and

https://confluence.atlassian.com/display/JIRAKB/JIRA+slow+and+throwing+error+There+was+an+error+getting+a+DBCP+datasource+in+logs

Please try to increase Java JVM with increments of 512Mb as instructed in https://confluence.atlassian.com/jira/increasing-jira-memory-5896.html

Hope these will help you resolve issue.

Regards

Chander

How much memory is it running with? Have you tried increasing that?

Tayyab Bashir

JVM has 250MB min. and 1GB max

Following are the 3 prominent errors occurring repeatedly in the logs. h4.

Ok, have you tried increasing the memory for it?

Tayyab Bashir

Yes its happening because of the bug watcher. Any idea how is this happening? And what can we do to prevent it? Because we do use bug watcher extensively. (until this happened)

Chander Inguva

As suggested by Nic above, contact Bug Watchers Support and report the issue of Memory Leak. https://marketplace.atlassian.com/plugins/com.metainf.jira.plugin.bug-watcher/server/support Support Link: http://www.meta-inf.hu/wiki/display/PLUG/Support;jsessionid=C43ADE445C8028FF6E51C9ED5D6A3D17
