Hi,
Our JIRA instance uses more than 80% of system memory.
It is not normal operation. How can i decrease memory utilisation?

now 98%!!
Uninistall apps, reduce the number of custom fields, users and projects you have. Simplify everything as far as you can.
Jira is a memory hungry application (because it does doe much). My question would not be about "Jira taking too much memory", but about whether you're running it on a machine suited for it. What heap size have you allocated, and what level of usage are you? (number of users and issues generally is the starting point for sizing)
Hi Nic,
Thank you for your reply. i have 100 GB memory in jira server!. About 90% of jvm is free(used: 2396 MB total:622222). There are about 3,000 users and 40000 issues.
What is resolution to decrease memory usage?
You don't have a memory usage problem if the JVM is showing 90% free.
What is the actual problem you are worried about here?
Windows server task manager show memory utilization 98% and system operation is slow.
If the JVM is showing 90% free, then the problem is elsewhere.
My guess here is that you've set the heap size too large for Jira and that is crowding out other processes Windows is trying to run, leading to a lot of swapping and CPU use dealing with it.
You say you've got 100Gb memory on the server, so that's half a question answered, but can you tell us the maximum heap size actually set for Jira?
It looks like you're new here. Sign in or register to get started.
