      When testing Infinispan Persistent Docker container (with RocksDB) we encountered very interesting problem. The container went up to 100% of memory limit and then was killed by the OOM killer. After removing RocksDB Cache Store the problem went away.

      After looking at dmsg it turned out that the container was killed because of the OOM. The interesting thing is that the OOM allows to process to keep using 100% of the memory but only for a short amount of time.

      The second thing we investigated are GC logs:

      It became clear that the JVM was killed while it was reclaiming space. Unfortunately it took a little while and OOM killer kicked in.

      The only missing bit is why it happened with Rocks DB? The answer is in System.gc() called while reinitializing the database. The test harness used cache.clear() method which cased that.

      The bottom line: if you are using persistent Docker image, please make sure you're not calling cache.clear() too often or (this is suggested solution) increase memory limits.
