Docker container with memory limits dies after adding RocksDB ------------------------------------------------------------- Key: ISPN-8141 URL: https://issues.jboss.org/browse/ISPN-8141 Project: Infinispan Issue Type: Bug Components: Cloud Integrations, Loaders and Stores Affects Versions: 9.1.0.Final Reporter: Sebastian Łaskawiec Assignee: Sebastian Łaskawiec 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: {code} 2017-08-01T10:06:33.421+0000: [GC (Allocation Failure) Desired survivor size 35651584 bytes, new threshold 2 (max 15) [PSYoungGen:

2017-08-01T10:07:10.509+0000: [Full GC (System.gc()) *** JBossAS process (179) received KILL signal *** {code} 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.
