The problems means that any NFS service from the server causes it to crash with 100% reliability. It will panic and dump core about 75% of the time. This basically means that nfsserver is unusable on this machine. dmesg, kernel backtrace and nfs tcpdump included. 192.168.100.1 is the 4.7-release client, and 192.168.100.44 is the 5.0-current server. pancake# dmesg Copyright (c) 1992-2003 The FreeBSD Project.
