<p class=MsoNormal><span style='color:#1F497D'>Thanks for the reply on this.
I’m glad you can confirm that it’s not my watchdog.conf which is causing the
problem. The watchdog script (/etc/default/watchdog) on my box looks like this:<o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>Does that seem normal to you?
Also, as a little additional information, the syslog entry when the box first
starts up for watchdog looks like this:<o:p></o:p></span></p>
