  ERROR DESCRIPTION:
   System went into a loop with VLTASK using all/most of the
   CPU resources, but no new LIC Logs we being logged.  Also,
   the DASD utilization was growing about 3% per hour.  Via
   a PEX trace we found that VLTASK was creating 8-page extents
   very quickly.  LIC Log & Streams I/O developers analyzed the
   MSD and found a loop in an SK module, but it was passed a
   bad pointer from an unknown source, causing a loop in the
   code module.
 
 
  LOCAL FIX:
 
 
  PROBLEM SUMMARY:
  The VLTASK went into a loop and was using all/most of the CPU
  resources, but no new LIC logs were being created.  Also, DASD
  utilization was growing at 3% per hour because the VLTASK was
  creating 8-page extents very quickly.  The loop was isolated in
  #skdirtn.
 
 
  PROBLEM CONCLUSION:
  The message formatting program (#skdirtn) has been changed to
  recognize and avoid an infinite loop when processing a chain of
  messages.
 
 
  TEMPORARY FIX:
 
 
  COMMENTS:
 
 
  MODULES/MACROS:   #SKDIRTN
 
 
  SRLS:      NONE
 
 
  RTN CODES:
 
 
  CIRCUMVENTION:
  None.
