APAR status

• Closed as program error.

Error description

• When running a large program, the resulting application produces
  a FS=30 FS2=8 error at runtime for ISAM files.
  

Local fix

• N/A
  

Problem summary

• USERS AFFECTED:
  COBOL users with large STL relative or indexed files and
  random/dynamic access maybe affected by this issue.
  
  PROBLEM DESCRIPTION:
  A flaw in buffer management could cause file corruption.
  
  It was possible to have the same offset in the file in both a
  data and index buffer; and which gets written last could vary.
  

Problem conclusion

• Buffer management has been corrected such that only one buffer
  at a time will have any given offset in the file.
  

Temporary fix
