during normal operation.

since root is nfs mounted, and it’s hung, nothing but power cycling works.

some more info:
the server is running 14.3 (i don’t think this is relevant)
the server us also providing /usr/local
if the host is running with a local root, all is fine.
virtual hosts, i.e bhive, also hang under similar configuration.

so now i'm running a tcpdump on the server, and will probably have more info.
