It logs to stdout.

I think the key will be figuring out which tdb the
runaway smbd is reading.

Probably.  Does ifconfig show an abnormal amount of errors?
If not, then you are probably ok wrt duplex settings, et. al.

And to clarify, when the smbd starts sucking up CPU, check to
which client it is connected to and look at the traffic
pattern from that client to see if the smbd process is doing
real work on behalf of the client.
