 The syslog.conf file is as follows (also at 
 http://intrepid.warped.com/~scotte/visible/syslog_ktrace/syslog.conf):
 
 # Intrepid syslog.conf file

 *.err;kern.*;auth.notice;authpriv.none;mail.crit	/dev/console
 kern.debug						/var/log/messages
 
 # The authpriv log file should be restricted access; these
 # messages shouldn't go to terminals or publically-readable
 # files.
 auth,authpriv.info					/var/log/authlog
 
 cron.info						/var/log/cron

 Adding some fprintf's in, and running syslogd in debug mode yields:
 
 Making unix dgram socket `/var/run/log'
 Listening on unix dgram socket `/var/run/log'
 Listening on kernel log `/dev/klog'
 Attempt to chroot to `/'
 Attempt to set GID/EGID to `0'

 That last "***SE spec:nmbd,smbd name:" repeats forever.  That appears to 
 be why it get stuck.
 
 Not sure why it'd get stuck there only the first time though. 
 Subsequent runs return:
