Yet one thing - the described node shutdown sounds me like some
watchdog driven shutdown - do you use heartbeat's watchdog capability
or some other external check which is able to panic the node?

No I don't, nothing fancy at all yet :)

Any thoughts on how I might troubleshoot this further? Syslog is killed
itself, so I don't have any information in the logs at all. Local
console is also booted out, so even sitting in front of the server
doesn't help.

I think it is either watchdog or some stonith method (power off/cycle the machine). You can try for example 'lsof | grep watchdog' to see whether the watchdog device is opened.

If you can supply your heartbeat, monit and scripts configuration as described Hauk, then it will be much easier to find the problem.
