All VM backups failing with 41 intermittently

Created: 30 Jan 2013 • Updated: 07 Feb 2013 | 4 comments

After upgrading to 7.5.0.4, Our VM backups are failing with error 41.

2 VM backup hosts All VMs divided between these 2.

Issue is the backup for all VMs hosted on either on these will fail intermittently.

On the backup host which is a media server, there are lot of bpbkar hung and not terminated even after job is finished. Suspecting that cud be the issue.

Master server: Linux 5.8, NB 7.5.0.4

Media server/Backup host: WIN 2008, NB 7.5.0.4

Fails after exactly 30 minutes 0 which i guess is your timeout setting

It you feel that it is an upgrade thing i will have a dig about as it rings bells (maybe need to use disableIPResolution to speed host name resolution up)

For now you could increase your timeouts to prevent the timeout causing you issues - this would be the client read timeout on the Media Server and / or the VMWare timeouts

All are covered in the VMWare Admin Guide - section 11 troubleshooting section

Hope this helps

Thanks for your response Mark.

The Timeout was already set to 1800 sec now we have moved it to 9600.

Lets see if backup fails again.

Will update

Hi,
As per mark, try disabling the IP resolution.

But remember, once you do this setting, you cannot use your client name as hostname or the IP addr.
