Increasing JVM memory results to Jira service unable to restart

[Erwin Manuel]

Hi,

We are able to increase JVM memory using: http://confluence.atlassian.com/display/JIRA/Increasing+JIRA+Memory

However, when we try to increase memory higher that 1280MB. Jira service is not able to restart anymore.

Is there any workaround for this? Thanks in advance

You will not be able to give more than 1.3G heap on 32bit windows. If you use Linux, you can likely allocate upto 3G. If you must stay with windows, as Jobin says, you'll need 64bit windows.

Bear in mind that this is normal heap we're talking about.

32 bits: -Xmx should be max 1460m

Linux: you need to enable hugemem to reach 4Gb processes (1Gb is used for mapping and max heap that can be allocated is around 2.5Gb)

Hi,

we have the same problem (Win 2003 server - 64bit, 6GB RAM, JIRA 4.4, bundled Tomcat) - unable to change default JVM memory size to JIRA service. After change from xms128m/xmx512m to xms512m/xmx1024m JIRA not able to start.

Yet not found correct solutions and reason of the problem, the only thing that partially help, was increase windows page file size. After it we can increase xmx to 1024m, but change of xms still leads to error.

Are you already running on 64bit JDK? I have not yet tried out the solution they suggest.

If you change memory settings and find JIRA console telling you nothing changed, what you did wasn't doing what you thought.

Just a hunch but Id guess the service config doesnt have the correct values, you have to uninstall, update config, reinstall service to make it stick (or hack registry).

It runs on bundled java in Tomcat. Values have changed - according JIRA start log file, but after start system has immediately shut down. We try both methods, change service setting and also configure it by registry. Could try service reinstall.

You probably need to look at the link you posted, check service details.

Are you using 32 bit JDK? If so, that explains it. Try to switch to 64 bit JDK and the problem will go away.

Can you supply the tomcat catalina logs and/or confluence logs showing JIRA not starting?

Also, how much memory is free on that machine before starting JIRA?
