yes, you should use TCP when running NFS over a WAN.

generally on these late kernels network partitions will
not cause issues that require a umount/remount sequence.
if you are unsure about the reliability of TCP, may i
suggest you use it with the "soft" mount option and a
high retrans setting (see the "mount" and "nfs" man pages).

(and btw, i agree with steve, if you can reproduce this
problem and capture a network trace, that would be helpful:
use "tcpdump -s0 -w /tmp/dump host server-name-here" to
capture a raw network trace).
