I don't know the answer to that, but I think setting

     samba kcc command = /usr/sbin/samba_kcc -d5

will turn up the log level on the samba_kcc subprocess itself and not on 
everything else.

samba_kcc should be running every 5 minutes, not every 2 hours, so I'd 
be looking for something else that is making your network seize up every 
two hours.

As it happens, 2 hours is the DNS record scavenging interval, but I 
don't see how that would affect this.
