Description

The attached reproducer shows the following exception during streaming data to cache:

[2019-02-21 16:15:23,202][ERROR][tcp-disco-msg-worker-[100a6976 0:0:0:0:0:0:0:1%lo:47500]-#19%3%][root] Critical system error detected. Will be handled accordingly to configured handler [hnd=StopNodeOrHaltFailureHandler [tryStop=false, timeout=0, super=AbstractFailureHandler [ignoredFailureTypes=UnmodifiableSet []]], failureCtx=FailureContext [type=SYSTEM_WORKER_BLOCKED, err=class o.a.i.IgniteException: GridWorker [name=data-streamer-stripe-5, igniteInstanceName=3, finished=false, heartbeatTs=1550754912905]]]
class org.apache.ignite.IgniteException: GridWorker [name=data-streamer-stripe-5, igniteInstanceName=3, finished=false, heartbeatTs=1550754912905]

If the blocked timeout is changed by cfg.setSystemWorkerBlockedTimeout(30_000), after streaming data and restarting several nodes the following critical error occurs:
