Description
Summary
During plugin (add-on) installs/updates (including license updates) /delete/disable action UPM will flush the large number of caches. Under high load that will cause significant JIRA performance degradation and might cause JIRA to freeze/stall for a long time.
Steps to Reproduce
- Apply high load to JIRA
- Upgrade any plugin.
Expected Results
- JIRA performs fast, could be slight performance degradation.
- JIRA admin is notified about the impact
Actual Results
- JIRA admin is not notified about the impact
- Thread dump might show the following thread UpmAsynchronousTaskManager:thread

Notes
Problem is amplified at JIRA Datacenter. Cache flush is triggered during node startup as UPM needs to register and load modules from plugins. See JRASERVER-66839
Workaround
Please plan any plugin actions updates/delete/disable (UPM actions) during low peak hours or maintenance windows. See Best Practices for Managing JIRA Application Add-ons for recommendations.
