CPU usage on Bamboo server high.... but is it normal?

We are running a small installation of Bamboo and JIRA on an Amazon EC2 m3.large instance.

JIRA works fine, but every so often the Bamboo java process hits 180% of CPU and stays there for 10+ minutes, making the UI virtually unusable (20+ seconds per click).

I've delved into various options and settings, but nothing seems to change the issue:

We are running an older build (Atlassian Bamboo version 4.2.1 build 3213 - 28 Aug 12), and are not in a position short term to update, though we will once our current release is out the door.

Any pointers appreciated!

I've been seeing the same thing after upgrading from 5.6-5.8

Same with us - 180% CPU usage all the time. No ideas?

If you restart bamboo, does it stop? If so, check out this.


I am assuming there is nothing in your bamboo logs showing thing like out of memory which would mean you need to increase jvm memory or virtual machine memory.

I noticed out-of-memory and plugin-timeout errors during log-scan. Will try memory increase.

And it failed to stop itself when I tried to stop Bamboo service. Had to "kill-nine" it. After restarting, CPU is at normal levels - but I am sure it will escalate to previous high levels in CPU usage, in a day or so.

P.S.: My Bamboo installation is latest current version as of time of this post.

It seems to be a java/linux issue as spotted here: http://stackoverflow.com/questions/11283271/jvm-always-beyond-100-cpu-usage-in-centos-6 

It happened for me to on CentOS 7.1 / Bamboo 5.10.3 / openjdk "1.8.0_51" and the fix worked.
