    Why don't JBoss Guys offer a solution to [TransactionImpl] T

    Thomas Hofmann Newbie

      Hi,

      we developed an high throuhput app (a lot of DB insert/updates). Some customers are using jboss in production for that app. But sometimes jboss reports the well known (!!) but unfixed error (warning?)

      16:08:57,977 WARN [TransactionImpl] Transaction TransactionImpl:XidImpl[FormatId=257, GlobalId=actout04/1530891, BranchQual=, localId=1530891] timed out. status=STATUS_ACTIVE

      and the processing of records stops. Each record is processed in a seperate tx! There is no exception or any other hint to find the reason for the problem. If the tx times out, I would expect a rollback, but the processing seems to hang. What can we do to fix this problem, especially if we can't reproduce this behaviour?


      I'v started a Solaris truss for the hanging process and it delivers some strange infos:

      and so on. Is there a deadlock? So to use Jboss in production mode, I hope Jboss guys can offer a solution.

      Thx in advance
