I guess it would certainly help if you could provide such information.
Just put some 'dsyslog()' calls into the main loop at several "strategic"
places and write a timestamp into the log file. Also write a message to the
log file when the watchdog hits. Maybe this can show us where the main program is
when the watchdog hits.
