Backup of VADP fails randomly and the frequency get higher with more client in the group

Hi everyone,

I have a strange issue going on right now with my NetWorker 8.2.2 while running VADP backup.  It is a new infrastructure that was built up from 0.  This environnement has two clients doing their backup on it, one of them has their VADP backup running just fine.

The other though, is another story.

We have configured over 40 clients  and run them individually in order to test them, all worked just fine. However, when i place them all in a group and start it, with or without parallelism, the entire group fails in less than 30 seconds, sending lots of errors messages.

We are still unsure, but we may have an authentification problem somewhere in the process.

I f anyone could help me try to figure out whats going on with those environnements, i'll be very nice.

Thank you,

Christian Carrier

If you can paste the error logs, it would be helpful.

Re: Backup of VADP fails randomly and the frequency get higher with more client in the group

Hello,

Just to tell you before putting in errors messages, as long as i run small group, not more than 3 clients, there are no errors.  I ran multiple time in a row backup of a group with 2 set of three clients in it: 4001/4003/4014 as well as 4950/4951/4952, every time all was ok and backup was taken successfully.

In order to obtain an error message, i placed in a group the six clients mentionned earlier: 4001/4003/4014/4950/4951/4952


I have run a group with 6 clients in it and here is the result:

Every single one of them failed with an error:

4001:
