Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of LDGW for OS/390 version 5       *
  *                 (release 1 and higher) that use FRCA caching *
  *                 are affected by this APAR.                   *
  ****************************************************************
  * PROBLEM DESCRIPTION: 10 instances of error message calls     *
  *                      send the parameters to the message      *
  *                      catalog in the wrong order.             *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  10 instances of error message calls send the parameters to the
  message catalog in the wrong order.
  This resulted in the juxtaposition of string and numerical data.
  Since these data are of differing lengths, the call to the error
  logging subsystem resulted in an abend of the queue manager.
  The error messages in question are only called under serious
  system errors (opening, stat-ing, reading a file that has
  already been successfully served) and they are not easily
  reproducible or testable except under highly unusual system
  conditions.
  

Problem conclusion

• The calls to the error logging routines were modifed in the code
  itself in order to correlate them with the expected syntax
  listed in the message catalog.  All changes were within the
  source file HTIPC.c.
  
  The following COMPID's are affected by these changes:
  5697D4300 LDGW for OS/390  Version 5 (release 1 and higher)
  
  The code changes are stored in CMVC under defect PQ37673
  
  Doc changes: none
