OA26569: MEMORY LEAK WHEN A REMOTE TEMS RECONNECTS TO THE HUB

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Environment:
  All platforms
  
  Problem Description:
     Memory leaks occurs in a remote TEMS when it reconnects to
  the HUB.
  
  The memory leak occurred in ko4crtsq.cpp's processNodeListUpdate
  method.
  
  The correction is the addition of a single line to do a delete
  of the
  remoteTable.  The following is a snippet of the area where the
  delete
  needs to be added:
  
  Line#
   6275   delete cacheTable;
   6276   delete hubTable;
   6277   delete remoteTable;    // This needs to be added
  
  
  The line number may vary depending the version of ITM source for
  this unit.
  
  Provide a detailed step-by-step recreation procedure.
     Configure a HUB and remote TEMS.  After the remote connects
  and completely initializes shutdown the HUB.  Wait the the
  remote TEMS detects that the HUB is no longer available then
  restart the HUB and let the remote reconnect to the HUB and
  completely initializes.
  
     The platform chosen to do the above was Windows.  An memory
  leak analysis tool called debugDiag.exe was used to measure the
  memory growth and it also identified the largest storage
  offenders along with the call stack.
  
  Related Files and Output:
     For Windows, viewing task manager for the kdsmain.exe process
  while recreating the memory leak would also be a good idea along
  with keeping notes.  eg.  TEMS start time, virtual memory.
  configuration files, coredumps, etc.
  

Local fix

• remote TEMS reycle will recover

  * PROBLEM DESCRIPTION: Memory leak occurs in an RTEMS when it  *
  *                      reconnects to the HTEMS.                *
  ****************************************************************
  * RECOMMENDATION: Apply the PTF.                               *
  ****************************************************************
  Memory usage increases in an RTEMS whenever it reconnects to
  the HTEMS. The amount of memory can be minor or significant,
  depending on the configuration of the RTEMS.
  

Problem conclusion

• The code was modified to release the storage in question when
  it is no longer needed.
