Yes, I think that initial problem was with communication and it need to be tested more on my side. But during handling this error, Ignite throw NPE, I think that NPE during communication exception handling is bug. [01:08:22] Possible failure suppressed accordingly to a configured handler [hnd=StopNodeOrHaltFailureHandler [tryStop=false, timeout=0, super=AbstractFailureHandler [ignoredFailureTypes=UnmodifiableSet [SYSTEM_WORKER_BLOCKED, SYSTEM_CRITICAL_OPERATION_TIMEOUT]]], failureCtx=FailureContext [type=SYSTEM_WORKER_BLOCKED, err=class o.a.i.IgniteException: GridWorker [name=grid-nio-worker-tcp-comm-2, igniteInstanceName=TestNode-0, finished=false, heartbeatTs=1591837692022]]] 2020-06-11 01:08:22,686 [nio-acceptor-tcp-comm-#16311%TestNode-1%] ERROR :135 - Critical system error detected.

От: akorensh Hi, This looks like a communication problem. GridWorker [name=grid-nio-worker-tcp-comm-3 Make sure all nodes can see each other. Test it with a minimum number of nodes. If it still doesn't work then describe your test and send the full logs and Ignite condifg. Thanks, Alex
