PK73152: LEAK IN COM.IBM.RMI.IIOP.CONNECTION WHEN NO_RESPONSES ARE THROWN

APAR status

• Closed as program error.

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.
