IZ33684: 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

• 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
