Hi, I'm testing Flink streaming but seems to have some problems with jvm core dumps. I haven't really looked at the heap dump yet. It seems to be related to the G1 GC.
If I want to go back to CMS-GC, do you have any preferred settings? # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x00007fa281df900d, pid=36541, tid=140335655700224 # # JRE version: Java(TM) SE Runtime Environment (8.0_45-b14) (build 1.8.0_45-b14) # Java VM: Java HotSpot(TM) 64-Bit Server VM (25.45-b02 mixed mode linux-amd64 compressed oops) # Problematic frame: # V [libjvm.so+0x5b900d] G1ParScanThreadState::copy_to_survivor_space(oopDesc*)+0x3d # # Failed to write core dump.
