  PROBLEM SUMMARY:
  The crash occurred while an Enterprise Extender link was
  retransmitting packets and the sequence number of the pipe
  wrapped.
  

Problem conclusion

• The root cause of the crash could not be determined
  with the data available. A code change has been made
  which are expected to prevent the crash and allow
  the software to continue functioning. Symptoms that
  may be seen if this problem is encountered could
  include failure of the RTP pipe and the sessions
  using that pipe. An ASSERT in nrtpstat.c line 981
  will be recorded in the sna.err log if this problem
  is encountered again.
  

Temporary fix

• sna_v5router64
