Try using truss(1) to trace the system calls that smbd is making. If
you're lucky this will give you sufficient information that you can
work out what's happening. Note that you might have to drop the `-D'
daemonize flag to get anything meaningful:
truss -o /tmp/smbd.truss /usr/local/sbin/smbd
There's also ktrace(1) which is the next level up in process tracing,
but significantly more complex. ktrace(1) can follow descendants of
the initial process and can generate large quantities of output so
read the ktrace(1) and kdump(1) man pages first and use with due
care and attention:
ktrace -id -f /tmp/smbd.ktrace /usr/local/sbin/smbd -D
kdump -f /tmp/smbd.ktrace | less
Cheers,
Matthew
