[tlug] Out of Memory: can't log in to my machine

[Jean-Christian Imbeault <jc@example.com>]

I have a RH machine running as a web server and this morning I came in 
to find the following message being repeatedly displayed on the root 
console:

Out of Memory: Killed process 13649 (httpd)

I can't even log in to the machine. I get the login prompt and can enter 
a login name but the password prompt never comes up.

Does anyone have any suggestions as to how I can log in to the machine 
without rebooting it? I would like to have a look around and see what 
caused this problem. I'm guessing it's something a user installed 
(possibly MySQL or a Perl cgi) and want to track this problem down.

Thanks,
