> Hi,
> we're occasionally getting stale data on remote EJB invocations (number counter returns number 1 lower than expected, see example). -This is usually preceded (~6 seconds before that) by cluster wide rebalance after a node is brought back from dead.-
> - 2000 clients, stale data is uncommon
> - requests from a single client are separated by a 4 second window.
> An example of stale data:
> {code}
> 2015/08/28 13:01:35:442 EDT [WARN ][Runner - 640] HOST perf17.mw.lab.eng.bos.redhat.com:rootProcess:c - Error sampling data:  <org.jboss.smartfrog.loaddriver.RequestProcessingException: Response serial does not match. Expected: 86, received: 85, runner: 640.>
> {code}
> And a link to our jobs if you're interested:
> https://jenkins.mw.lab.eng.bos.redhat.com/hudson/job/eap-7x-failover-ejb-ejbremote-jvmkill-repl-sync/5/console-perf17/consoleText
> This behavior has so far been observed with jvmkill and undeploy scenario, on REPL-SYNC and DIST-SYNC caches.
