Subject [jira] [Created] (FLINK-4193) Task manager JVM crashes while deploying cancelling jobs
Date Mon, 11 Jul 2016 14:12:10 GMT
Gyula Fora created FLINK-4193:

             Summary: Task manager JVM crashes while deploying cancelling jobs
                 Key: FLINK-4193
                 URL: https://issues.apache.org/jira/browse/FLINK-4193
             Project: Flink
          Issue Type: Bug
          Components: Streaming, TaskManager
            Reporter: Gyula Fora
            Priority: Critical

We have observed several TM crashes while deploying larger stateful streaming jobs that use
the RocksDB state backend.

As the JVMs crash the logs don't show anything but I have uploaded all the info I have got
from the standard output.

This indicates some GC and possibly some RocksDB issues underneath but we could not really
figure out much more.

GC segfault

Other crashes (maybe rocks related)

The third link shows 2 issues that happened in parallel...
