Windows Server 2012 R2 Crashing during Backup

[j.bohlmann]

Hello,

i have a big problem with Veeam Backup & Replication 9.0 (all updates are applied). When the daily backup Job is running the whole Hyper-V Server is crashing. I watched it via the iLO remote contro. It seems that the network connection is dropping first. As soon as the network connection starts having trouble the whole server freezes. Veeam displaying 0 kb/s at the current job.
After a few seconds the boot screen appears...

The whole server is running since 6 Month including Veeam Backup & Replication 9.0. No Problems at all.
The error occurs since two Days (No Windows Updates applied). No changes to all VM's since more than 5 days.

Details of my Hyper-V Host:

HP Dl380 G9
2x Xeon 2630V3
128GB RAM
16x 600GB SAS RAID 10
2x 400GB HP Smart Cache RAID1 (for the RAID10)
HP 561FLR 10GBE Network Card
Server 2012 R2 inkl. all updates
SQL 2012 Express ink. all updates

VM's:
1 DC
1 Exhchange
1 Applikationserver
1 Fileserver (The Server crashes at this Point at about 1TB)
1 small linux Server

I hope you can help me. My holidays are planned for Monday and of course this error appears when i plan my holidays.. especially 3 days before holidays...

Hi Josh,

While we are waiting for the support engineer to reply, can you please review Windows Event log at the time when this server crashes? Do you see any error messages?

Thanks!

Hello,

i've recreated the backup job and that fixed my problem. I cannot understand how this can crash the full hyper-v host but okay.

Thanks

Maybe job settings are different, thus you see a different behavior. In any case, if you're able to update this topic with your support engineer findings that would be appreciated by future readers. Thanks!

As you note a networking dropping off before the Physical OS hanging would you please ensure HP Firmware / Drivers / Software are all current? Intelligent Provisioning and HP Service Pack for ProLiant should be able to assist with this.
