Unrecoverable "..DummyTransaction{xid=DummyXid{id=437353}, status=3} is not in a valid state.." after " Unable to acquire lock after 15 seconds" ------------------------------------------------------------------------------------------------------------------------------------------------ Key: WFLY-9448 URL: https://issues.jboss.org/browse/WFLY-9448 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 10.1.0.Final Environment: Centos Reporter: jamie smith Assignee: Paul Ferraro Priority: Major On our system, after some time we get this: javax.ejb.EJBTransactionRolledbackException: ISPN000299: Unable to acquire lock after 15 seconds for key UnknownSessionID [4957576549555554536866505268565165695766655070536957516655656852] and requestor GlobalTransaction:<node1>:682146:local. Lock is held by GlobalTransaction:<node1>:681890:local And then we start getting the following: ERROR [org.infinispan.interceptors.InvocationContextInterceptor] (default task-2) ISPN000136: Error executing command GetKeyValueCommand, writing keys []: java.lang.IllegalStateException: Transaction DummyTransaction{xid=DummyXid{id=437353}, status=3} is not in a valid state to be invoking cache operations on. at org.infinispan.interceptors.TxInterceptor.enlist(TxInterceptor.java:395) ... ERROR [io.undertow.request] (default task-2) UT005023: Exception handling request to /contextpath/someXYZResource: java.lang.IllegalStateException: Transaction DummyTransaction{xid=DummyXid{id=437353}, status=3} is not in a valid state to be invoking cache operations on. continouously on most requests without being able to recover. After restarting, again if at some point the "Unable to acquire lock after 15 seconds" happens, we start getting errors about the DummyTransaction, which never stop. I believe "Unable to acquire lock after 15 seconds" should not lead to an unrecoverable state. NOTE: Each node runs with: `./standalone.sh -c=standalone-full-ha.xml -u=239.255.200.215 -b=$localIp -bmanagement=$localIp -bprivate=$localIp -Djboss.node.name=node1 -Djboss.socket.binding.port-offset=200` . `jboss.node.name` and `$localIp` only changes between nodes.
