Thanks. I am working on getting those details. The issue that is being seen is that the link is "Lost" and requires a reboot to recover, I say "Lost" as they have not provided system logs that confirm the physical link is actually going down.
They Isolated it to only happening when the VPN software is installed. It does not even have to be enabled, just installed on the system. If they uninstall the software the issue stops happening.
It is very random and happens at multiple sites and home users that have a 10Gb home router, so there is no common switch, router or cable involved. Just this specific vendor NIC and the VPN software.
Is there any logging that can be collected to indicate what the software is seeing when this happens?
