Problem

A VMware client will intermittently fail to generate a snapshot, causing the NetBackup job to fail with a status 156.  Examining the bpfis log on the VMware Backup Host revealed the error shown.  However, when the client was accessed and the Event Viewer / Application and System logs were examined, there was no evidence of any VSS or related issues.  A vssadmin list writers command returned no errors.

Error Message

bpfis log with vmcloglevel = 6 (see VMware for NetBackup Administration Guide for more information on vmcloglevel)

"An error occurred while quiescing the virtual machine. See the virtual machine's event log for details. <178>"
