Similar to AMQNET-487, deadlock. Thread 58 had a network exception, most likely trying to ACK a message: “Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host..”
And somehow, thread 58 and 68 got into a fatal deadlock.
Debug log attached.[^debuglog.txt]
