[jboss-jira] [JBoss JIRA] Commented: (JBAS-1761) Clustering unit test failures

[Brian Stansberry (JIRA)]

Brian Stansberry commented on JBAS-1761:
----------------------------------------

Final resolution of this involved the following:

1) Remove all up and down threads from the tc5-cluster.sar TCP stack, and all but one (up) thread from the cluster-service.xml stack.  Removes random latency I'd seen that caused failures of timing sensitive tests.
2) Added TCP.tcp_nodelay to cluster-service.xml TCP stack, where having nagling enabled was leading to timeout of a test that made >10,000 synchronous RPC calls.
