Lock files in version 1.11.11

[Zanabria, Moises]

Guys,
I'm trying to figure out what's what my problem is,  since I upgraded my cvs
binary I'm getting a bunch of cvs lock files and those are leaving in the
repository.

My last cvs server version was 1.11.5 and I've just upgrade to the latest,
in the past I was working with CVS 1.11.5 in the server and cvs 1.11 client
for  several Unix flavors, but since I've migrated the binary to 1.11.11 and
use the same (cvs 1.11) in the cvs co process or commit process the lock
file is not going away.

please let me know if that particular issue would solve if I upgrade the
client as well..if so what about the WinCvs Binary??

I ran the a trace and this is what I got:

The first time has been succeeded.  The second case failed.

S-> system('/local/cvscore/bin/logcheck.pl' '/tmp/cvsBfxwCc')
S-> rename(CVS/Entries.Backup,CVS/Entries)
S-> unlink_file(CVS/Entries.Log)
S-> Parse_Info (/home/p4cvs/src/CVSROOT/verifymsg,

check, not ALL)
S-> unlink_file(/tmp/cvsBfxwCc)

,v, 1.8, , -ko, /tmp/cvsnwyJm4)
Terminated with fatal signal 11
-> rename(CVS/Entries.Backup,CVS/Entries)
-> unlink(CVS/Entries.Log)

any clues.
Thanks.

Moises.
