APAR status

• Closed as program error.

Error description

• There exists a rare condition where server can crash if a
  'protect stgpool pool_name type=local' process fails due to an
  'out of space' error condition.
  
  The activity log reports a 'protect stgpool' process failing
  before the crash occurs:
  
  ANR0200E PROTECT STGPOOL process xx failed due
  to insufficient space in destination storage pool. (SESSION:
  xxx,
  PROCESS: xx)
  
  This is an example when the target server is out of storage pool
  space.
  
  
  dbx on AIX shows a stack similar to:
  
  pthread_kill(??, ??) at 0x900000000569f14
  _p_raise(??) at 0x900000000569764
  raise.raise(??) at 0x900000000039ae8
  abort() at 0x9000000000564e4
  PsAbortServer(??) at 0x100015420
  pkAbort(??) at 0x10000c8e0
  pkDestroyMutex(??) at 0x1000086d0
  SdFreeChildCtlDesc(??) at 0x100c81250
  SdLocalProtectEndSubProcesses(??) at 0x100c76100
  sdProtectionStgThread(??) at 0x100c7271c
  StartThread(0x0) at 0x10000da90
  
  
  This rare condition exists when 'out of space' condition occurs,
  and two threads
  attempt to free the same memory structure.
  
  
  
  
  
  IBM Spectrum Protect versions affected:
  Server 7.1.3.x and higher, and 8.1.x and higher on all supported
  platforms
  
  
  
  Initial Impact: Medium

Local fix

• Ensure there is sufficient space for 'protect stgpool' to
  complete successfully.
