[Nagiosplug-help] Nagios crashes badly and takes out both machines!

[Pedro Silva]

Try running the machines without Nagios if everything goes well then
Nagios is the responsible for that crash. Otherwise something else is
making the machines go down.

After The test without Nagios, if thew machines won't crash you should
try to disable some plugins to see if they are responsible for those
problems.
