I bet you need to investigate increasing timeout values, but I know not
which.

Could you give us some hints on what to look for in the logs and what kind
of tuning that might be? I too have a UNIX environment and when I use the
procedures defined in the Troubleshooting Guide to resolve the 4x status
codes, everything comes up normal.

Regards,
Dennis

We see these as well in Unix environments.

I would check the logs on the master/media servers at the time the error
occured (/usr/openv/netbackup/logs).

It may well be some network tuning is required to cater for more concurrent
clients.

I imagine our setup here is somewhat 'typical' for a large environemnt.
100Meg systems feeding 1Gig networks to a L700 tape silo.

A few times a week, I have NetBackup fail a backup with an error 4x code
(some kind of transient network error). These always seem to be on NT
machines (proportionally, there are more NT than Unix, so it might not be
directly related).

Looking at the network itself, I cannot find any switches reporting errors
between the client and the server. Netbackup On sebsequent attempts,
NetBackup is successfull in completing the backup.

Has anyone else seen this behaviour?

Jason
