hyper-v Hyper-V issues on Windows 2019 host

[jotajota]

Hi!
I'm looking for help in this matter (apologies in advanced for my English, not my native language)

Recently migrated a few VMs to a different host running Windows Server 2019... I set up VSS (24 hours, 8 RP) and replication to another host running Windows Server 2019.

The thing is I'm getting this weird errors on some of the VMs

 

Hyper-V failed to generate VSS snapshot set for virtual machine 'SRV-XXX': This operation returned because the timeout period expired. (0x800705B4). VSS snapshot set generation can fail if backup operation is in progress. (Virtual machine ID 180E42ED-058D-46DB-A5A2-8E91342A6F5A)

And, on a particular VM - Windows Server 2012 r2 (which is a FS and we have shadow copies set up) I'm getting a few errors... one is that the VSS process hangs and the computer freezes (no explorer to interact or whatsoever, file sharing works tho) in this case I've to do a reboot and it will fix the error. Checking the logs I'm getting this error:

 

Faulting application name: DPMRA.exe, version: 4.2.1603.0, time stamp: 0x59dcc367

Things I've already tried:

- deleted all the shadow copies on the server

- reinstall DPM agent

- disable Shadow Copies on the server did make a difference, but it's not an option

May someone around can help me out 

 

Thanks!"
