are there any log files for cvs client/server connection information?

[Teala Spitzbarth]

Recently we had a cvs co command 'hang' and we are trying to debug what
happened.  The server side (RH 6.2 running CVS 10.7) show no processes
running, but the solaris side (Solaris 8, running CVS 1.11) still shows
the cvs co in process.    So somehow the server side closed the connect,
but the client side hasn't groked that.

Any log files that we can look at to debug this?

Thanks
