    [~andrew.tolbert] discovered an issue while running endurance tests on 2.2. A Node was not able to start and was killed by the OOM Killer. Briefly, Cassandra use an excessive amount of memory when loading compressed sstables (off-heap?). We have initially seen the issue with system.hints before knowing it was related to compression. system.hints use lz4 compression by default. If we have a sstable of, say 8-10G, Cassandra will be killed by the OOM killer after 1-2 minutes. I can reproduce that bug everytime locally. * the issue also happens if we have 10G of data splitted in 13MB sstables. * I can reproduce the issue if I put a lot of data in the system.hints table. * I cannot reproduce the issue with a standard table using the same compression (LZ4). Something seems to be different when it's hints? You wont see anything in the node system.log but you'll see this in /var/log/syslog.log: {code} Out of memory: Kill process 30777 (java) score 600 or sacrifice child {code} The issue has been introduced in this commit but is not related to the performance issue in CASSANDRA-9240: Here is the core dump and some yourkit snapshots in attachments. I am not sure you will be able to get useful information from them. core dump: Not sure if this is related, but all dumps and snapshot points to EstimatedHistogramReservoir ... and we can see many org.apache.cassandra.metrics:... exceptions in system.log before it hangs then crash. To reproduce the issue: 1. created a cluster of 3 nodes 2. start the whole cluster 3. shutdown node2 and node3 4. writes 10-15G of data on node1 with replication factor 3. You should see a lot of hints. 5. stop node1 6. start node2 and node3 7. start node1, you should OOM. //cc [~tjake] [~benedict] [~andrew.tolbert]

    Look for missing class files, specially org.I0Itec.zkclient.IZkStateListener.
