Error description

• Error Description:
  During a VM backup, the Tivoli Storage Manager client scheduler
  may crash when there is a low memory condition.
  Customer/L2 Diagnostics:
  The following entry will be reported in the dsmerror.log prior
  to crash as an indicator of low memory:
  ANS0361I DIAG: calloc() failed: Size <size> File

  Initial Impact: Low
  Tivoli Storage Manager Versions Affected:
  6.4 and 7.1 Windows and Linux x86
  Additional Keywords:
  TSM VE
  

Local fix

• Increase the amount of memory available to the client or if a
  non default VMMAXPARALLEL value is being used, lower this value
  to reduce client memory requirements.
