TimeoutException: Replication timeout when handling request with DIST cache

    XMLWordPrintable

Details

    Description

      Seen in http-session scenarios with DIST cache only. REPL cache scenarios seem not to be affected.

      TimeoutExceptions occur right away after sending first request and definitely result in client getting 500:

      I was able to reproduce it even with a very small load of 30 sessions.

      Server link (run with 30 sessions):

      This issue occurs under different conditions than JBEAP-3779 (which is similar), that's why I opened new issue.
      Number of occurrences of TimeoutExceptions is very high. The server logs are full of them.
      This issue makes clustering with DIST cache unusable, thus giving blocker priority.

      Also, there is a issue with shutting down the servers in the end of the test, I don't know if it can be related, but I am hitting it constantly in the http-session DIST scenarios.
      The server shutdown usually gets stuck on this command:

      [JBossINF] [0m[0m04:38:51,694 INFO  [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (MSC service thread 1-7) ISPN000082: Stopping the RpcDispatcher for channel web

      EDIT:
      Also ejb-remote tests with DIST cache are affected (even if only 20 sessions are created).

      Server log for ejb-remote run:
      http://jenkins.mw.lab.eng.bos.redhat.com/hudson/job/mvinkler_eap-7x-failover-ejb-ejbremote-shutdown-dist-async/3/console-perf20/

      Client log for ejb-remote run:
      http://jenkins.mw.lab.eng.bos.redhat.com/hudson/job/mvinkler_eap-7x-failover-ejb-ejbremote-shutdown-dist-async/3/console-perf17/

      EDIT #2:
      Can be very easily reproduced locally. Just start a cluster of at least 3 servers with clusterbench deployed. Then do few requests to various nodes until you get 500 as a response. Also notice, when shutting down a node, which logged TimeoutException before, the node won't stop and get stuck during the shutdown.
