Problem Summary

JIRA Software Development Integration Plugin might create large number of ListenableFutureAdapter threads (10k+) and that cause JIRA to stall and crash.

Environment

• Instances with a large amount of issues (1 million+) and linked to (D)VCS accounts.

Steps to Reproduce

1. Create instances with a large amount of issues
2. Link to DVCS accounts with valid content (Bitbucket server or other)
3. Trigger web-hook update-summary to update many issues (5k+) Dev-status

Expected Behavior

JIRA operates normally

Actual Behavior

If large number of issues are requested to update Dev-status, there will be large number ListenableFutureAdapter threads and whole JIRA instance stalls and crashes.

Other symptoms:

• High CPU utilizations
• High disk activity due to active Lucene reindexing.

Notes

• Thread dump collected during that time will show large number of ListenableFutureAdapter threads with following stack:

• REST API webhooks /rest/dev-status/1.0/webhooks/update-summary

Workaround

• Reduce number of webhooks call
• Disable Development Integration Plugin (com.atlassian.jira.plugin.devstatus)
