org.infinispan.util.concurrent.TimeoutException: Timed out waiting for topology ------------------------------------------------------------------------------- Key: WFLY-4865 URL: https://issues.jboss.org/browse/WFLY-4865 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 8.2.0.Final Reporter: Ian Kent Assignee: Paul Ferraro Fix For: 9.0.0.Final We have a 10 ode wildfly cluster. We recently started getting the following exceptions in one of our deployment environments. I checked wildfly docs, google, wildfly jira and wildfly forums and cannot find a resolution. We are using default configuration for jgroups and we are using a replicate async web cache. {noformat} 2015-07-02 14:31:16,628 ERROR org.infinispan.interceptors.InvocationContextInterceptor (clojure-agent-send-off-pool-10600) ISPN000136: Execution error: org.infinispan.util.concurrent.TimeoutException: Timed out waiting for topology 43 2015-07-02 14:31:24,613 ERROR io.undertow.request (default task-27) UT005023: Exception handling request to /fault/elements/Node%3ABGVLPAAMT1A-P-AL-0294-01/monitoring-state/history: java.lang.IllegalStateException: Address 10.70.19.243:10.70.19.243-0/web is no longer in the cluster {noformat} The fact that this only happens on one of our clusters leads me to believe that it is environmental (maybe network latency).
