Hi @olivierlambert @bleader
thank you both again for the detailed replies and suggestions. I’d like to provide a bit more context about our setup and situation:
Situation Summary:
We’re currently running XCP-ng 8.3 with Xen 4.17.5-13 on a mix of servers, including some older, obsolete hardware.
Interestingly, XCP-ng 8.2 runs without issues on identical hardware configurations — no crashes, even under the same workloads.
On this particular host, we’ve experienced 10 crashes so far, and in almost every case the crash happened while performing delta backups from Xen Orchestra.
This seems to consistently trigger the issue under higher network load.
We’ve already performed full memory tests (memtest86+) on this host, and the results came back clean — no memory errors found.
The servers are currently physically located at a remote site, which makes immediate hands-on intervention difficult.
We’re organizing a visit to the site to update the BIOS and potentially replace the Realtek NIC with a supported Intel NIC as suggested. This intervention will happen as soon as logistically possible.
Question:
Is there anything else you would recommend we check or do remotely in the meantime before our on-site intervention?
And once we're physically on-site, aside from:
Updating the BIOS
Swapping NIC hardware
is there anything else you’d recommend we inspect or collect while we’re there?
I appreciate your help and guidance — and thank you again for pointing us in the right direction so quickly.
ONE more important question which guest tools do you recommend for Win server 2019, 2022, windows 10 ?
is 9.4.0 right one?
