IT31060: BACKUP VM CRASHING TSM CLIENT WHEN BACKING UP VCENTER SERVER VMGUEST.

APAR status

• Closed as program error.

Error description

• When a snapshot create task fails for a VM and, we fail to
  receive failure information from the vcenter related to that
  task, this causes the Spectrum Protect client to also not
  provide a proper return code for this process. The result is a
  crash with a stack similar to:
  Call Stack:
