[jboss-jira] [JBoss JIRA] (AS7-6397) Cluster Environment Web Session Locks

Cluster Environment Web Session Locks ------------------------------------- Key: AS7-6397 URL: https://issues.jboss.org/browse/AS7-6397 Project: Application Server 7 Issue Type: Bug Components: Clustering Affects Versions: 7.1.1.Final Environment: Windows 7 64bits, 8 GB RAM Reporter: Manuel Pinto Assignee: Paul Ferraro Hi, I found a problem with web session locks in a cluster environment. We have two Liferay 6.1.1 nodes (over JBoss 7.1.1 Final) in standalone-ha.xml configuration with infinispan "web" cache-container, replicated-cache and file store. The load balancer is configured in non sticky session mode. Problem: when a node processes requests in some cases locks the session and never unlock it, preventing other node from processing requests for that session. The affected node never regain the locked session and keep throwing the following exception for all subsequent requests and only recover a session when other node shutdown: Note: we also tried invalidation-cache and distributed-cache and all locking modes but without success. 17:39:00,174 ERROR [org.apache.catalina.connector.CoyoteAdapter] (http--172.16.250.105-8080-4) An exception or error occurred in the container during the request processing: java.lang.RuntimeException: JBAS018060: Exception acquiring ownership of Cvn-K+r-cBGesIBoDrakJhrO at org.jboss.as.web.session.ClusteredSession.acquireSessionOwnership(ClusteredSession.java:528) [jboss-as-web-7.1.1.Final.jar:7.1.1.Final] at org.jboss.as.web.session.ClusteredSession.access(ClusteredSession.java:496) [jboss-as-web-7.1.1.Final.jar:7.1.1.Final] at org.apache.catalina.connector.Request.doGetSession(Request.java:2625) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.connector.Request.getSession(Request.java:2375) [jbossweb-7.0.13.Final.jar:] at org.jboss.as.web.security.SecurityContextAssociationValve.invoke(SecurityContextAssociationValve.java:81) [jboss-as-web-7.1.1.Final.jar:7.1.1.Final] at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:155) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:368) [jbossweb-7.0.13.Final.jar:] at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:877) [jbossweb-7.0.13.Final.jar:] at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:671) [jbossweb-7.0.13.Final.jar:] at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:930) [jbossweb-7.0.13.Final.jar:] at java.lang.Thread.run(Thread.java:662) [rt.jar:1.6.0_32] Caused by: org.jboss.as.clustering.lock.TimeoutException: JBAS010223: Cannot acquire lock //default-host//Cvn-K+r-cBGesIBoDrakJhrO from cluster at org.jboss.as.clustering.lock.SharedLocalYieldingClusterLockManager.lock(SharedLocalYieldingClusterLockManager.java:439) at org.jboss.as.clustering.web.infinispan.DistributedCacheManager.acquireSessionOwnership(DistributedCacheManager.java:372) at org.jboss.as.web.session.ClusteredSession.acquireSessionOwnership(ClusteredSession.java:520) [jboss-as-web-7.1.1.Final.jar:7.1.1.Final] ... 12 more The standalone-ha.xml "web" cache-container config is the following: <cache-container name="web" aliases="standard-session-cache" default-cache="repl"> <transport lock-timeout="60000"/> <replicated-cache name="repl" mode="SYNC" batching="true"> <file-store/> </replicated-cache> <replicated-cache name="sso" mode="SYNC" batching="true"/> <distributed-cache name="dist" mode="ASYNC" batching="true"> <file-store/> </distributed-cache> </cache-container> Thanks, Manuel Pinto
