Message NODE_X::MESSAGE_Y not found in retransmission table in REPL stress tests

This WARN message was seen in stress test scenarios stress-session-repl-sync and stress-session-repl-async in server logs:

07:14:56,291 WARN  [org.jboss.as.clustering.jgroups.protocol.NAKACK2] (thread-2) JGRP000041: perf18: message perf19::367290 not found in retransmission table

Message occurs during the test on all the nodes (more than 150 000 occurences on each node) always after cluster-wide rebalance finished:

07:11:39,119 INFO  [org.infinispan.CLUSTER] (remote-thread--p5-t5) ISPN000336: Finished cluster-wide rebalance for cache clusterbench-ee7.ear.clusterbench-ee7-web-passivating.war, topology id = 6

It seems the message occurs more frequently at the end of the test.

This error started occuring in DR12 builds and is probably causing performance drops and sampling errors in a repl-async scenario.

The message is the same as in failover test scenario ejb-ejbservlet-jvmkill-repl-async (JBEAP-9000).
