Hi, According to the provided log I see "Blocked system-critical thread has been detected" message and that the node was segmented since it was unable to respond to another node. Most probably it's caused by JVM pauses, possibly related with GC.
Do you collect GC logs for the nodes? You can find an information how to enable GC logs here: https://ignite.apache.org/docs/latest/perf-and-troubleshooting/troubleshooting#detailed-gc-logs Igor -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
