Tomcat service is running high CPU (99%) everytime visit to none admin pages in JIRA 5.0.2

Ganga_Selvarajah

Hi,

I am facing an issue the “Tomcat” service is running high CPU (99%) everytime visit to none admin pages in JIRA. If I go to admin pages then the CPU usage is dropping to 1-2%.

Please note that, I am using Apache 2.2 as a web server, its connecting to AJP port 8009 via http.

JIRA version 5.0.2

O/S: Windows 2008 Server R2

Database Server : MS SQL 2008 R2

I can’t find the any information on the log file. Could you please help us!

Thanks

Ganga S

In the event of high CPU consumption by Tomcat, you can create a few thread dumps, and check the output in the log. This is how to do it - http://confluence.atlassian.com/display/JIRA/Generating+a+Thread+Dump

If you need assistance to review the thread dumps, you can contact Altassian Support. Remember to attach the logs as well.

after I have changed the AJP reverse proxy settings in JIRA server.xml, then the tomcat service is running normal.

This settings has an issue, the CPU usage for tomcat always 100%

Then I have changed to this settings, the CPU usage for tomcat normal and jira running without any issues.

Could you tell me, what are the issues in the settings?

Thanks

The minProcessors and maxProcessors parameters are deprecated. I suggest you look here - http://tomcat.apache.org/tomcat-5.5-doc/config/http.html#Standard_Implementation

its very easy to promote a DOS attack to JIRA server.

I face this trouble for at least 4 years... already contacted Atlassian support, and local consultant partners for on site health check analysis.

The answer for this problem always is: upgrade.

so when you do an upgrade, and have same problem, then always there is a new version, s othe answer is, upgrade... it is an infinite loop.

ok.. try jira 8... have the same problem, and then Atlassian will ask to pay for a datacenter.

the real problems is ; JAVA

the second one: TOMCAT

but ok, for 99,9% os customers that user only 10 fields an jira default workflow will never have any problem.

for 0.1% pay for a datacenter and start to pray.. no money back if do not work.

that's the way to become millionaire !
