Excessive RAM consumption (10GB+)

Question

Hi,

Just installed fresh version of Jira on a linux machine. Followed the Linux install guide as to get through the process.

After Jira has booted and was configured with some initial users we have notices that RAM allocation for JIRA processes was 10.9GB, used RAM was under 2GB.

Have never seen this before on other fresh JIRA installs.

Can anyone advise as to why would JIRA allocate over 10GB of RAM. Also how could we limit it?

Also the same is with Confluence.

Thanks in advance

Hi Daniel,

Please see the attached photo. I also have pmap log files for Jira and Confluence if that may help in figuring out the solution.

Thank you for the links. I read through them and in the System Info I can see that  the JVM Memory statistics show Total Memory at 738MB and used at 469MB - which is great.

What makes us nervous is that the htop unix utility is showing that the JIRA processes allocate 10.9GB of RAM.

Hi @dainius.narsutis

This is quite strange. I haven't seen this behaviour with fresh installations of Jira. What version of Jira are you installing?

Follow the guides below to set memory usage on both applications -
