Dan D [https://community.jboss.org/people/norad_2] created the discussion "Distributed session cache locking problem" To view the discussion, visit: https://community.jboss.org/message/728357#728357 -------------------------------------------------------------- I have a cluster of jboss servers running behind a vip. The session cache uses infinispan and is configured below:             <cache-container name="web" aliases="standard-session-cache" default-cache="sso">                 <transport lock-timeout="60000"/>                 <replicated-cache name="sso" mode="SYNC" batching="true">                     <file-store/>                 </replicated-cache>             </cache-container> I am seeing the following error show up sporadically. It does not happen every request but when it happens the request fails. 2012-04-04 19:57:26,627 ERROR [http--0.0.0.0-4080-1] [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host]] {} {} Exception sending request initialized lifecycle event to listener instance of class org.jboss.weld.servlet.WeldListener: java.lang.RuntimeException: JBAS018060: Exception acquiring ownership of kkTs5N-UGggp3VngthDv4X+L           at org.jboss.as.web.session.ClusteredSession.acquireSessionOwnership(ClusteredSession.java:528)           at org.jboss.as.web.session.ClusteredSession.access(ClusteredSession.java:496)           at org.apache.catalina.connector.Request.doGetSession(Request.java:2625)           at org.apache.catalina.connector.Request.getSession(Request.java:2375)           at org.apache.catalina.connector.RequestFacade.getSession(RequestFacade.java:841)           at org.jboss.weld.context.beanstore.http.LazySessionBeanStore.getSession(LazySessionBeanStore.java:72)           at org.jboss.weld.context.beanstore.http.LazySessionBeanStore.<init>(LazySessionBeanStore.java:58)           at org.jboss.weld.context.http.HttpSessionContextImpl.associate(HttpSessionContextImpl.java:31)           at org.jboss.weld.context.http.HttpSessionContextImpl.associate(HttpSessionContextImpl.java:16)           at org.jboss.weld.servlet.WeldListener.requestInitialized(WeldListener.java:134)           at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:143)           at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102)           at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109)           at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:368)           at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:877)           at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:671)           at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:930)           at java.lang.Thread.run(Thread.java:722) Caused by: org.jboss.as.clustering.lock.TimeoutException: JBAS010223: Cannot acquire lock //default-host//project/kkTs5N-UGggp3VngthDv4X+L 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)           ... 17 more Is this a known issue?
