Most likely your vfs module is crashing Samba. Do you see any messages
about SEG Faults in /path/to/log.client name?

Also, you can do the following. Add 'panic action = "/bin/sleep
99999"' to the smb.conf and then when you see the problem see if there
is a process with sleep 99999 there.

Also, since you have a level 10 log for the client, what does it show.
Do you have any debug statements in your vfs module functions so you
can be sure you are making it into those functions?
