Try running the NMBD process interactively instead of detached, and see 
if it writes anything useful on the console.

The starting of the NMBD process is not keyed to anything in the 
SMB.CONF.  It is started by a command file prior to starting the rest of 
SAMBA and run as a detached process (in 2.0.6).

I do not know what 2.2.4 does, I have not looked at the source.

But it appears that NMBD will need to become a TCP/IP started process in 
order to avoid deadlocks in the 2.2.x and later streams from my previous 
investigations.  See the list archives for details.

That would indicate a problem with the logging system.  It stopped in the
middle of an entry.

My guess is there is an ACCESS VIOLATION lurking around their somewhere,
indicating a bad pointer was passed to the snprintf() routine.

You might want to look at NMBD_WORKGROUPDB.C for that debugging 
statement in the SAMBA UNIX source.  The 272 should help you find it.
