    org.jboss.cache.lock.TimeoutException

    Manish Bhatia Newbie

      Hi,
      We are using JBoss Cache 1.3.0 with JBoss AS 4.0.3SP1. We face this lock timeout exception when there is high load on the cache.

      Any help on this issue will be highly appreciated

      This is what the exception looks like
      Caused by: java.lang.RuntimeException:

      This is how our JBoss Cache configuration looks like.
