If it is a process that is still running,  you should be able to find the
process with 
`ps options |grep cvs` where options are either "aux" or "ef".

If he has done all the those things, which should be unnecessary, and the ps
netted nothing ... some how cvs (on the server) was terminated while he was
doing his tag search and was not given a chance to clean up after itself.

with all the above going on I would:
1) configure inetd or xinetd to not run any more cvs processes while I
figure out what is going on. (and restart [x]inetd)
2) stop any currently running cvs instances (under linux on the server)
        `killall -SIGTERM cvs;echo "nice kill done"; \
        sleep 60; killall -9 cvs; echo "lets se-em survive that"`
        #if you get any output before the "nice kill done" echo, 
        #there were no cvs's running.
3) make a backup of the repository.
4) run Donald Sharp's check_cvs script to see what if anything is amiss with
the repository
5) take note of and delete any locks check_cvs finds.
6) decide if you want to fix anything else check_cvs finds.
7) take some guesses as to how it got into this state 
(this seems like a very weird state to me, it would probably be good to let
the mailing list know what version of cvs you are running on the server and
Tortoise. have you ever had this search for all tags action work in the
past?)
8) put the system back on line for cvs work. reconfigure [x]inetd to run cvs
pserver and restart [x]inetd.

9) you might want to check and make sure everyone is accessing the repo
through pserver or ext (to the same server machine) and that no one is
accessing it using a filesystem method.
