PH58609: RECURSIVE CALL ERROR WHEN AN EXCEPTION OCCURS

APAR status

• Closed as program error.

Error description

• When two different main COBOL programs running in CICS make use
  of the same COBOL sub-program; and when one main COBOL program
  produces a data exception, the second main COBOL program fails
  to run with a recursive call error similar to the one below:
  
  _iwzWriteStderr: call CICS msg routine...
  IWZ064S  A recursive call to active program CSOM4600 in
  compilation unit CSOM4600 was attempted.
  

Local fix

• N/A
  

Problem summary

• USERS AFFECTED:
  Users who have large complex COBOL programs that involve
  multiple levels of dynamic CALLs and who experience a user
  exception might by affected by this issue.
  
  PROBLEM DESCRIPTION:
  When a user exception occured, the COBOL Runtime was incorrectly
  tracking the use count of the open shared library. As a result,
  upon another use of the same
  shared module results in a recursive call error message.
  

Problem conclusion

• The COBOL Runtime has now been fixed to properly handle the use
  count of dynamicall opened modules so that the recursive call is
   not issued.
  

Temporary fix
