Anyone experiencing session hosts becoming unavailable at random
Ebot_H Still working through this with MS, funny enough, their latest update appears to be pointing to a HW failure on AMD 64-bit CPU EPYC 7763 which is run on their servers cause by the GPU driver that's integrated with the CPU.
They are advising to update the graphics drivers on the VM, although that's not possible since our VMs are not GPU enabled and it's just using the Citrix display adapter.
So something running on the VM could be causing the HW failure with the type of AMD CPU used in the hosts.
They've asked for a couple more things to check, it's totally random failures though, we haven't had any for a week or 2. I wouldn't be surprised if some of the hosts in Azure are missing updated HW or GPU drivers and sometimes the VM's just happen to run on an out of date one causing the failure....
- Thanks for the info. I tried switching to Intel after seeing your message but it didn't help at all, so perhaps don't waste too much time on that avenue. I'll let you know if we find anything.
- Must be Microsoft going down another rabbit hole. These issues with vms crashing on avd we still have vms onprem on 2k19 and never see any of these failure types.
Hi, did you find a solution to this? We have the same problem and have now tested both intel/amd VM with and without autoscaling, but the problem remains.
Very grateful for more info. Have a case with Microsoft but getting nowhere.
