Hi. Having irregular issues with OID timeouts on WS2022 with ConnectX-5/6 cards.
Windows detects a problem and resets the adapter after 5 timeouts, which isn’t pretty on a busy Hyper-V server.
The events look like this:
“The network interface “Mellanox ConnectX-6 Dx Adapter #3” has begun resetting. There will be a momentary disruption in network connectivity while the hardware resets. Reason: The network driver did not respond to an OID request in a timely fashion. This network interface has reset 1 time(s) since it was last initialized.”
“NDIS initiates reset on device Mellanox ConnectX-6 Dx Adapter #3.”
It is listed as a known issue in the WinOF-2 driver (#1336097 at Known Issues - NVIDIA Docs).
So, we wanted to raise the timeout per the instructions, problem is “Max OID time” or anything similar isn’t listed in the registry keys list or anywhere else in the manual or adapter properties in Windows, so we have no idea what/where to change that.
