PI08983: WHEN FORMATTING THE LM DOMAIN (LOCK MANAGER) VIA IPCS A LOOP IS ENCOUNTERED WHEN PROCESSING THE LMQUICK1 CELLS.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You are running CICS TS 3.2 and looking at a dump of CICS in
  IPCS. When issuing:
  VERBX DFHPD650 'LM'
  to format the lock manager domain, a loop occurs formatting
  the LMQUICK1 cell.  It repeatedly puts out the same entry -
  .
  LMQUICK1 <address> LOCK MANAGEMENT DOMAIN QUICKCELL 1
  .
  In this case it was associated with the BCB_LOCK.
  When trying to MAX to the bottom of the output, you may receive:
  
  IPCS DETECTED A SHORTAGE OF VIRTUAL STORAGE
  
  Additional Symptom(s) Search Keyword(s): KIXREVrer
  ABEND878 CPU increase looping
  This is the same as APAR PM99804 for 5.1 and PM96818 for CICS
  TS V4

  ****************************************************************
  A customer is using IPCS to format LM domain LMQUICK1 cell, but
  a loop is encountered and eventually an S878 abend. In DFHLMDUF,
  the buffer for QUICKCELL_1 is allocated after a GET_BLOCK, but
  it may be reused after a subsequent FORMAT_BLOCK call. If this
  happens, the QUICKCELL_1 does not contain valid contents and
  and this may lead to the loop and S878 abend.
  
  When using IPCS in batch, using DFHPD650 with LM=2 or LM=3
  would normally result in an S322 abend combined with:
  
  $HASP375 jobname ESTIMATED  LINES EXCEEDED
  $HASP375 jobname ESTIMATE EXCEEDED BY  n LINES
  
  Additional keywords: ABEND878 ABEND322 MSG$HASP375
  

Problem conclusion

• DFHLMDUF has been changed so that the QUICKCELL_1_NEXT is saved
  before it calls DFHDUFUT again.
