-------------------------------------
Summary: Deadlock in CompactionStats.writeNode during online
compaction
Key: OAK-4555
URL: https://issues.apache.org/jira/browse/OAK-4555
Project: Jackrabbit Oak
Issue Type: Bug
Components: segment-tar
Affects Versions: Segment Tar 0.0.2
Reporter: Valentin Olteanu
Attachments: stacktrace.log
While running online revision cleanup under high load, the instance reached a
deadlock (or possible infinite loop).
Full thread dump is attached, but it seems that:
1. Thread-21 tries to commit -> CompactionStats.writeNode -> locked by
compaction thread
2. TarMK compaction thread tries to compact -> print statistics -> infinite loop
