linux/solaris/whatever.... NOT windows is the important bit.

And what process has ID 24576 and, more importantly, who owns it.

If nobody else is running cvs/cvsnt/cvslockd, it could be a few zombie
processes... just kill them. IIRC this happened in 2.5.03... the 2.5.04
branch seems a bit better :-)

FWIW, if you are getting zombie cvslockd processes and you can't upgrade to
a newer version of cvsnt, set up a cron job to pkill any cvslockd processes
every 24 hours or so.

Good grief... a new box doesn't cost that much (and running your cvs system
on a non-dedicated server is just asking for trouble).

Ah, the joys of working for a one of those corps.

There's an option in /etc/cvsnt/PServer to specify the port (
LockServer=localhost:2402 ... specify the port appropriate)

Fair enough.
