System Hang


Hi, my REMOTE system has somehow been in a deadlock state, I can't SSH into it. It's not a network problem, as I am able to ping it.

Now my question is, what can I do? I can't do anything to it physically because it's miles away.

Is there a way to prevent this from happening in the future? Like a way to detect this and if it happens, the system will automatically reboot or something?

OS: RH 7.2

I think it might be a BUG in PHP and Apache that is causing this hang. It was right after I ran a PHP script.

I dont know about detecting and rebooting. But if the problem is with not being able to login an option is to redirect the console to the serial port and read this from some other machine. So if the system is hung, the console will be still accessible.

The problem is not getting any responses from the system, I think the system is in a state where CPU is 100% so nothing is responding. As for the serial port, I can't do that as the system is miles away.

I'd just like to know if there is a way (crontab script) maybe that detects this state and then reboot the system if necessary.
