+.SH SIGNALS

+In version 1.9.18 and above, nmbd will accept SIGHUP, which will cause it to dump out
+it's namelists into the file namelist.debug in the SAMBA/var/locks directory. This
+will also cause nmbd to dump out it's server database in the log.nmb file.
+Also new in version 1.9.18 and above is the ability to raise the debug log
+level of nmbd by sending it a SIGUSR1 (kill -USR1 <nmbd-pid>) and to lower
+the nmbd log level by sending it a SIGUSR2 (kill -USR2 <nmbd-pid>). This
+is to allow transient problems to be diagnosed, whilst still running at
+a normally low log level.
