GUI, ssh access broken - else working

[Kofl]

Hi,

we are running our OPNsense on Hyper-V for month, and every x weeks, the GUI is no longer working and access via ssh is broken (seems the ssdh daemon is down).

Firewall routing is still fine, also openswan is working as expected.

So far we also cant login via console, it hangs after entering "root" for the login.

The console output only shows:

hvvss0: Unknown opt from host: 4

Did anyone experience a similar behavior?

OPNsense version = 18.7.5

Thanks,
Thomas
