This is new, and concerning. Usually FreeBSD is pretty stable, but 15.1 had this happen shortly after I added a new virtual network interface through ESXi server.
I only added the new virtual interface (hotswapped) a few moments ago. Something I've done countless times in previous versions and other OS's. It's not even configured yet. Maybe it has something to do with my vnet jails running inside the virtual machine?
