Cache recovery fails due to missing responses --------------------------------------------- Key: ISPN-2802 URL: https://issues.jboss.org/browse/ISPN-2802 Project: Infinispan Issue Type: Bug Components: State transfer Affects Versions: 5.2.0.CR3 Reporter: Radim Vansa Assignee: Dan Berindei Fix For: 6.0.0.Alpha1 When the cache recovery is started, the new coordinator sends CacheTopologyControlCommand.GET_STATUS to all nodes and waits for responses. However, I have a reproducible test-case where it always times out waiting for the responses. Here are the logs (TRACE is not doable here, but I added some byteman traces - see topology.btm in the archive): http://dl.dropbox.com/u/103079234/recovery.zip The problematic spot is on node3 at 05:37:57 receiving cluster view 34. All nodes (except the one which is killed, in this case node1) respond quickly to the GET_STATUS command (see BYTEMAN Receiving - Received pairs, these are bound to command execution in CommandAwareRpcDispatcher), but some responses are not received on node3 (look for Receiving rsp bound to GroupRequest). JGroups tracing could be useful here but it is not available (intensive logging often blocks on internal log4j locks and the node becomes unresponsive). As mentioned above, the case is reproducible, therefore if you can suggest any particular BYTEMAN hook, I can try it.
