Definitely strange problem.
I (and the people who use the machines I admin) do checkouts to directories
shared through NFS all the time (both on the NFS server and many NFS clients)
using :pserver: and :ext: cvs methods.

have you looked in /var/[log|adm]/* for any messages that happened around that

glitching and recovering with the same timing as your problem.
