IBM Spectrum Protect Server V8.1 Fix Pack 13 (V8.1.13) Downloads

APAR status

• Closed as program error.

Error description

• On an IBM Spectrum protect server running on AIX only, issuing
  'DELETE VOLUME' or 'AUDIT VOLUME' commands against volumes
  within a copy storage pool,
  may see the dsmserv process using an increasing amount of
  memory. A memory leak occurs in the bfResolveSuperBitfileEx
  module as allocated memory is not freed correctly after
  processing
  and may cause spectrum protect server to crash.
  
  Customer/Support Diagnostics:
  
  
  Reviewing servermon or separately captured SHOW ALLOC data from
  SP Server admin command line
  before, during and after delete volume / audit volume command
  will show increasing value of bytes
  stored against the bfResolveSuperBitfileEx module:
