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
