IBM Tivoli Network Manager IP 3.9.0 Fix Pack 4, 3.9.0-TIV-ITNMIP-FP0004
IBM Tivoli Network Manager IP Edition 3.9.0 Fix Pack 5, 3.9.0-TIV-ITNMIP-FP0005

APAR status

• Closed as program error.

Error description

• Core dump of ncp_g_event on solaris whilst performing isolated
  suppression.
  
  Memory corruption is occurring as a result of a bug in SunStudio
  11. There appears to be a problem with the std::deque STL
  container in the version of SunStudio used to build 3.9. This is
  Oracle issue CR 6363210: std::deque memory corruption. This is
  fixed in subsequent patched versions of SunStudio, to be
  integrated into the build system for future releases of ITNM.
  
  Symptoms:
  The symptom of this bug is a core dump of ncp_g_event on solaris
   in any current release of 3.9. It affects no other platforms.
  
  Under normal usage, the core dump will provide a stack trace in
  inconsistent places, as the issue involved is one of memory
  corruption. It typically appears as a problem whilst trying to
  allocate memory, but in a variety of areas of the code.
  
  Using memory profiling tools (eg libumem), the stack trace will
  show the issue in the CNCPDynamicGraphBreadthFirstSearch class.
  

Local fix

• The fix is to use a different STL container, a std::list, for
  the affected part of the RCA processing
