Hi Rick,
I've rebuilt the userland, of course.
# ls -l /lib/libc.so*
-r--r--r-- 1 root wheel 1234432 Jun 15 01:04 /lib/libc.so.7
# ls -l /boot/kernel/kernel
-r-xr-xr-x 1 root wheel 12010608 Jun 15 01:38 /boot/kernel/kernel
Further info to diagnose the problem:
I've got 3 NICs on 35, 135 and 235 (different subnets).
Netmasks are:
- xx.xx.xx.35/25
- xx.xx.xx.135/26
- xx.xx.xx.235/26
Client is xx.xx.xx.150/26. But you can try it with a single server.
A mount on 127.0.0.1 won't work either.
Here relevant part of rc.conf:
nfs_server_flags="-t -n 4 -h xx.xx.xx.35 -h xx.xx.xx.135"
mountd_flags="-l -r -h xx.xx.xx.35 -h xx.xx.xx.135"
/etc/exports:
/usr/export/src -maproot=root -ro -network xx.xx.xx.128 -mask 255.255.255.192
And here what I changed (rpcbind_flags) and the effects.
Notice, I executed rpcinfo each time before restarting nfsd and mountd.
Maybe I don't understand the rpcinfo output, because it differs from sockstat.

---------------------------------
Hmm... the mount has been successful, but I wonder why umount still gets a time out...
Need more info?
