Answer 1

From your error message, it looks like your transaction is simply
          timming out after 5 minutes. Why its timing out under load is a
          specific problem to your application. You might be getting some thread
          locking where one thread is waiting to obtain a lock on a bean instance.
          To determine if its thread locking, do a cntrl-break on the console
          and look for "wait" in the thread dump. Or, your application's business
          logic may just be too inefficient causing a transaction to take more
          than 5 minutes, hopefully this isn't the case. If is is Thread Locking,
          weblogic really doens't have a solution. Currently we are trying to
          employ "read-only" beans to eliminate thread locking on entity beans
          that are mainly used for reading information. Implementing "read-only"
          is done by setting cache-strategy to Read-Only in the XML deployment
          descriptor.
          Hope this Helps,
