Limit Jira Memory Amount

[steffenbleul]

Jira does not take my memory settings into account, how can this be?

I have set JVM_MINIMUM_MEMORY to 256m and JVM_MAXIMUM_MEMORY to 400m.

After startup Jira logs:

Maximum Allowable Memory                  : 356MB
         Total Memory                                  : 285MB
         Free Memory                                   : 231MB
         Used Memory                                  : 54MB

Later in startup Jira logs:

2017-05-04 09:28:47,540 JIRA-Bootstrap INFO      [c.a.jira.startup.LauncherContextListener] Memory Usage:
    ---------------------------------------------------------------------------------
      Heap memory     :  Used:  236 MiB.  Committed:  390 MiB.  Max:  390 MiB
      Non-heap memory :  Used:  217 MiB.  Committed:  236 MiB.  Max: 1264 MiB
    ---------------------------------------------------------------------------------
      TOTAL           :  Used:  453 MiB.  Committed:  625 MiB.  Max: 1654 MiB
    ---------------------------------------------------------------------------------

How can this be?

How do I effectively control Jira memory usage?

Hi Steffen 

The recommended heap size depends on 'n' number of factors. 

You can refer the below documents from Atlassian.

2. Increasing JIRA application memory

Thanks, Vishnu.
