Error description

  • Error Message: Customer setup has a very small request timeout
    value on the client side. The client sends out multiple requests
    in quick succession, most of which do not receive a reply within
    the time out period.
    The logs reveal a lot of requests timing out(CORBA.NO_RESPONSE
    exception).
    And the heapdumps taken on the client 30 -60 mins after the test
    reveal a persistence of com.ibm.rmi.iiop.IIOPInputStream
    objects.
    .
    Stack Trace: N/A
    .
    

Local fix

Problem summary

  • This leak happens because the reply messages received after the
    request time out period are not cleared properly.
    

Problem conclusion

  • The Connection object which holds the reply fragments has been
    modified to clear fragments corresponding to timed out requests.
    This fix is available in 1.4.2 SR13 and 5.0 SR9
    

Temporary fix

  • Increase request time out (com.ibm.CORBA.RequestTimeout) to a
    value that ensures that the replies are received within that
    time.
