  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When HPEL is enabled the SIP Container tried to create a
  session for logs. In some cases that caused a
  NullPointerException.
  

Problem conclusion

• The SIP Container uses the session repository to print SIP
  sessions in HPEL rather than trying to create a new
  session if it does not exist.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.5.  Please refer to the Recommended Updates
