APAR status

• Closed as program error.

Error description

• When performing a sort of large files, if the machine where the
  sort is being run on does not have enough tmp or disk space (or
  if the ulimits are low), then the exe SEGVs instead of issuing a
  useful error message.
  

Local fix

• N/A
  

Problem summary

• USERS AFFECTED:
  COBOL for AIX users with STL relative or indexed files may be
  affected by this issue.
  
  PROBLEM DESCRIPTION:
  A missing error check could cause a SEGV. There was a code path
  that did not properly propagate write errors; typically for
  ulimit or quota exceeded scenarios.
  

Problem conclusion

• The fix was to improve the error detection and propagation for
  such scenarios.
  

Temporary fix
