[infinispan-issues] [JBoss JIRA] (ISPN-6721) SuspectException when stopping and starting nodes in an embedded cluster using invalidation

[ https://issues.jboss.org/browse/ISPN-6721?page=com.atlassian.jira.plugin.... ] Karl von Randow updated ISPN-6721: ---------------------------------- Description: We run a cluster of four app servers on Tomcat with embedded Infinispan for Hibernate L2. When we bring down one of the app servers it shuts down that cache and then exits. On other nodes we frequently, although not consistently, receive SuspectExceptions from other nodes stating that the cache isn't running on the shutting down node. Similarly when starting a new app server we get the same. This feels like a race condition during startup and shutdown of the caches. Does that sound likely? There are two stacktraces below. I note that the shutdown example fails in {{JGroupsTransport.java:798}} which is when the response was suspected. While the startup example fails in {{JGroupsTransport.java:795}}, which is a {{CacheNotFoundResponse}} response. Here is a shutdown exception: {code:java} May 27, 2016 3:05:01 PM org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet [default] in context with path [] threw
