    Hi All,

    In my application threads are creating, because of this application is working slow.

    0000002d ThreadMonitor W WSVR0605W: Thread "WebContainer : 65" (000001f2) has been active for 654744 milliseconds and may be hung. There is/are 10 thread(s) in total in the server that may be hung.

    Hi Chinna,

    It is a db connection problem, did you check your connection pool availability and db connection performance?

    Regards,
    Ahmed

    Check with your Databaes Administrator to tune the performance.
    - indexes on db2
    - dbcachedresults setting in websphere etc..

    are you seeing only slowness or any of those threads getting blocked ?
