JIRA not responsive, high cpu load. Threaddump attached

Hello,

we're running quite an old JIRA instance and since today we cannot really work with JIRA (and the server its running on) as it procudes quite a high cpu load (~80%)

The JIRA issues itself are non responsive and will not load until a couple of minutes (even than, its simple gambling if its working or not)

 

I attached a threaddump after I restarted JIRA.

Before this attempt to restart JIRA we were able to access it for an hour or two until it got really slow again.

 

Some setup information:

JIRA v6.0.1#6096-sha1:e4a48bd

on:

Ubuntu 12.04

12GB RAM (DDR2)

CPU (???)

Non VM enviroment.


Thanks for any help.

You gave stats for the system, can you give stats for how you have sized the JVM.

execute in bash to find out CPU information:

$ cat /proc/cpuinfo

Hi Pascal,
If you're currently in maintenance you can open up a support ticket at https://support.atlassian.com, and one of our engineers can look into this if you like. 

Cheers
