The problem of JIRA Memory

yunfengg

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:

Issues	129694
Projects	496
Custom Fields	110
Workflows	27
Attachments	77885

Simply throwing more memory at a JVM is not a good answer. You need to look at what the problem actually is.

Hi Yunfeng

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

I wonder why Code Cache and PS Old Gen occupies about 98% now

Because you're not giving it enough room in your memory settings. Try changing them as per the doc I linked to.

@Nic, Can you give me some suggestion about the memory configuration both for JIRA and DB based on my JIRA enviroment(We deployed it on a Linux server(128G memory) and DB is oracle and is on a VM (128G memory), the detail usage information as you can see below)
