IT33674: DSMAGENT MAY CRASH AT THE END OF VM BACKUP OR WHEN CANCEL VM BACKUP.

APAR status

• Closed as program error.

Error description

• Problem Description:
  DSMAgent may crash at the end of VM backup
  or when cancel VM backup.
  The crash can occur in rare
  cases.
  
  The issue can occur when all are true:
   a. When an user
  trying to backup a vm with a different uuid than the one on the
  server for that vm. So the user get a UUID conflict message.
  
  b. The system is low on memory (RAM) so when IBM Spectrum
  Protect releases memory, it is quickly reused by the OS. (this
  explains the "rare" part)
   c. Backup for that vm fails or is
  manually stopped after conflicting uuid rc code is set,
  
  The
  cause of the crash is incorrect processing of the message for
  the RC_VM_UUID_CONFLICT return code.
