I did this on my boxes, but it does not help.
Again a device is _pingable_, but all daemons are
not responding anymore:
So either:
- watchdog was killed and this just disabled the watchdog timer altogether.
- watchdog was not killed for some reason (e.g. because the kernel
considered that it
would'nt it be senseful to adjust START=01 to
/etc/init.d/watchdog
and place something like this?
pid=$( pidof watchdog )
echo 1000 /proc/$pid/oom_score_adj
yeah, could do this.

I think jow wrote something like this already, see:
http://luci.subsignal.org/trac/browser/luci/trunk/contrib/package/freifunk-watchdog
Interesting, but has the same design-issue like already mentioned:
