On windows logs I found:
The computer has rebooted from a bugcheck. The bugcheck was: 0x0000003b (0x00000000c0000005, 0xfffff8000a8c4ce3, 0xffff848f31524a40, 0x0000000000000000). A dump was saved in: C:\WINDOWS\MEMORY.DMP. Report Id: 34f4e739-31a2-446c-b6ab-997ef65308c5.

So I am worried about happening again. They have been running fine for 21 days (from the install date).

Any suggestions are welcome?

Hey

In the same time of your error, what 's saying your Host ?

 

[ozgurerdogan]

Hey
Nothing in pve logs. Only in windows logs. Could this be something with ballooning (ksm)?

 

[Pifouney]

Hum, If it's was a balloning cause, you'll see it in your syslog

Lasts OS Win need a real BIOS update if you're on a production server running older than 2 year Maybe check in this way ?

Anyone from pve team?
