[jboss-jira] [JBoss JIRA] (WFLY-5437) Occassional stale data with remote EJB invocations and sync cache

Occassional stale data with remote EJB invocations and sync cache ----------------------------------------------------------------- Key: WFLY-5437 URL: https://issues.jboss.org/browse/WFLY-5437 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 10.0.0.CR1 Reporter: Richard Janik Assignee: Paul Ferraro Priority: Major 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-... This behavior has so far been observed with jvmkill and undeploy scenario, on REPL-SYNC and DIST-SYNC caches.
