Our JIRA is facing high response time issue, and when i look into the system info, i found the the memory is going to be used up. But we set 8G to JVM before and the issue has no been occured.
In addition, i found the PS Old Gen occupied 100%. So i need to know what's the root cause and how do we configure the memory of JIRA
BTW,here is the info of our JIRA:
As well as going back to a smaller overall memory space and then building up slowly as Zulfadli says, you need to tune the rest of the settings in line with each increase. It really is not as simple as just throwing more memory at it, there are consequences. You need to read up on Java memory tuning.
Can I ask you if you have got 32 bit or a 64 bit jira installation. And which version of jira you are on.
Note that on a 32 bit installation there is a capping (around 1.25GB) on the amount of memory that you can allocate to jira. If you are on a 32 bit then i recommend upgrading your jira installation to 64 bit
