Cause
Sometimes the error "Hazelcast instance is not active" is shown when Bitbucket Server is not available due to out of memory errors. Check the atlassian-bitbucket.log file for errors like:
java.lang.OutOfMemoryError: PermGen spaceOr:
java.lang.OutOfMemoryError: GC overhead limit exceededIf you see those then follow the resolution steps.
Resolution
- Shutdown Bitbucket Server.
- Follow this guide to increase Bitbucket Server available memory.
- Start Bitbucket Server and see if this issue happens again.
