My wild guess is cron or anacron or something like that is running
something that is somehow interfering with Samba.  What happens around
that time?  What's in /var/log/messages, /var/log/syslog,
/var/log/daemon.log, etc?

OK, but can you find anything that always seems to happen around the same time?

Otherwise, try to figure out why the "executable could not be found
for process 4170" happens.  If you could get a stack trace out of it
someone might be able to help you figure out what's going wrong.
