Summary
Windows is reporting a low virtual memory condition for the Jira Tomcat process:
1
Windows successfully diagnosed a low virtual memory condition. The following programs consumed the most virtual memory: tomcat8.exe.x64Environment
Jira running in a virtual Windows environment.
Diagnosis
Slow page loading or other performance issues.
Repeated low virtual memory conditions were reported on the Windows Event Viewer.
A high percentage of swap space is used which can be found in the
<total-swap-space>and<free-swap-space>in the Support Zip.
Cause
Java will use more RAM outside of the allocated heap as outlined in Run Jira Server in a virtualized environment. Excessive memory overcommitment can cause the OS to read/write memory to disk which can introduce performance issues.
Solution
A number of steps can be taken to resolve this behavior:
Review the Jira applications installation requirements and heap usage to increase the Jira application memory by small amounts (256mb) to verify if the problem is still occurring.
Increase the minimum page size of the paging file.
If the issue persists after taking these steps, please reach out to Atlassian Support with a Support Zip from your environment.
