I include very small piece of information in my first letter and now i
continue: I made some expirements...
I try to execute the next command with trace enabling (cvs export -d lib -r
bserver_v_1_1 MGD/COMMON/bserver/bserver/lib) and i have the next dump:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> BEGIN TRACE DUMP

Terminate batch job (Y/N)? ^C

I seem that cvs fully complete but hung at last operation (what is one?),
because we have checkouted or exported a normal file, but something wrong
from cvspserver side.

Original first message:
We have cvs pserver on Linux RedHat 7.3
server run string in xinted configuration:
cvs -f --allow-root=/home/cvs/repository --allow-root=/home/cvs/internal
(we support two repositories)

We try to export with command:
cvs export -d lib -r bserver_v_1_1 MGD/COMMON/bserver/bserver/lib

and command may be successful or no successful, when command not successful
we have one zombie process on a linux machine (where cvspserver are ran)
and client command wait infinitely, it can be interrupt by the Ctrl+C and
all cvspserver processes are exited...

ps output:
100 S sergey   10990   799  0  75   0    -  1328 schedu 09:58 ?

We use config option

Has anybody who can describe why cvspserver processes sometimes hunging?
Any ideas will be apprected.
Thanks in advance
