Hi,
Is there any way to reboot a server that I can't access via ssh, http, ftp or any port? But I can ping, traceroute & nmap it just fine. I have no idea what is causing this lockup or lock out, even after a reboot by the DC there's nothing in the logs to show what happened. :(
regards tom
Is it possible the machine is changing to a runlevel other than 3? This almost sounds like some of the firewall boxen I've heard of that basically shutdown to deny access to everything, yet the firewall/routing remain up and working.
Mike

It doesn't appear to be changing runlevels (how would it by itself?), nothing at all in the logs from when it stops working to when it reboots (after pushing the button).

I've been running into this on one of my RHEL3 servers. Pre-existing processes continue to run, but everything else (including logging) just stops. Rebooting from the power switch is the best I can do in that situation.
If anyone has suggestions where to start trying to debug, I'd be happy to listen.

Is there anything common between your two servers? Let's look at your hardware comparisons.

These 3 boxes are production servers (no X), I have others with similar configurations and some different which this is not happening to.
