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

  • This defect will be fixed in:
    1.4.2 SR13
    1.4.2 SR13 (Linux AMD64)
    1.4.2 SR13 (Windows AMD64)
    1.4.2 SR13 (z/OS 64-bit)
    5.0.0 SR9
    .
    The Connection object which holds the reply fragments has been
    modified to clear fragments corresponding to timed out requests.
    .
    To obtain the fix:
    Install build 20081018 or later
    

Temporary fix

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