OFO: Snapshot error (0x46b): A potential deadlock condition has been d

[SaleemK]

 I am running Veritas Backup Exec on a win2k3 sp3 server. All my remote servers seem to backup fine. The box I have veritas loaded on will backup the system state but when it gets to the C: drive set it fails with this error. "OFO: Snapshot error (0x46b): A potential deadlock condition has been detected." I tried backing up that system as a remote system and that failed with the same error. If anyone has ever ran into this before or just knows the solution I would apperciate any help.

Open the backup job properties, click on "Advanced Open File option" and select Microsoft VSS as the provider for the backup. On a Windows 2003 server, VSS would be a preferred provider in comparison to Symantec snapshot provider. This error is caused by Symantec snapshot provider. So, changing to VSS should take care of the error.

Please mark it a solution, if this is useful.
Thanks

I think it is a resource error, whether not enough memory or not enough free hard drive space if using Advanced Open File option.  I had 1 SQL server that is taxed and had this error frequently.  I have since turned off OFO and haven't had the problem. One other thing you can try is moving the Backup Exec OFO folder on the remote server to another server with more room. This will slow the backup however.  Adding more ram or moving the job to a time less busy or adding a slave hard drive and moving the OFO folder there may be a good option.  Hopefully this gives you some food for thought. Try some combination of suggestions above until find one that works.
