All other nodes then throw the following exception: Error obtaining the sorted input: Thread 'SortMerger Reading Thread' terminated due to an exception: Connection unexpectedly closed by remote task manager 'dyingnode' ... However, there are no error messages in the log of 'dyingnode'. But in the PID thread dump of 'dyingnode' I found this: # A fatal error has been detected by the Java Runtime Environment: # # SIGBUS (0x7) at pc=0x00003fff701afa4c, pid=1119228, tid=0x00003ff38a3ff1b0 # # JRE version: OpenJDK Runtime Environment (8.0_101-b14) (build 1.8.0_101-b14) # Java VM: OpenJDK 64-Bit Server VM (25.101-b14 mixed mode linux-ppc64 ) # Problematic frame: # J 433 C2 org.apache.flink.runtime.util.DataOutputSerializer.write(I)V (40 bytes) @ 0x00003fff701afa4c [0x00003fff701afa00+0x4c] # ... What can cause this? And is this Flink related? Best regards, Malte
