Stephan Ewen commented on FLINK-4193:
-------------------------------------

One of the crash reports looks like it could be G1 GC related. G1 is known to 
still have some issues in most Java 8 versions.

Can you try a different GC, see if that problem still occurs.

> 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
