Hi guys,
While using Jira 6 and so on, I've had no such problems, but after upgrade from Jira 6.3 to Jira 6.3.4, immediately tomcat started using all CPU (2 virtual cpu's) full (almost 100%). When no one is using Jira, cpu (tomcat) usage is about ~2% and when any jira user opens any page, usage immediately jumps to 80% - 100% percents untill page is loaded and dear God it takes a looong time to load that page. Even though the page is only pressed to "reload". Using processexp showed that the problem is that tomcat creats MSVCR100.dll threads (~100 threads) that overuse cpu. After searching for any solutions i've increased jira Java memory sizes as follows:
set JVM_MINIMUM_MEMORY=384m
set JVM_MAXIMUM_MEMORY=3768m
Although, there are a lot suggestions what to do, being an average computer administrator i do not actually know where to begin and what i need to find in catalina logs or so. Also, I didnt quiet understand how to make a dump file for this problem.
Virtual Machine Windows 7
4 GB Ram
2 CPU's
Jira version 6.3.4
Only 1 application running on Tomcat 7
Can anyone direct me to the solution? Catalina.log: http://pastebin.com/VpgpFsvQ.
