Linux server locking up
I've been running Django on MySQL on a Linux server for about 3 months w/o any problem. Suddenly a couple days ago, the server Django began throwing errors about not being able to connect to MySQL, at which point the entire server seizes up. The Apache Web server stops serving pages and SSH seizes up as well.

However, I can still ping the machine and it responds in a timely manner.

I don't think it's a configuration issue w/ Apache or Django or MySQL, since the SSH console locks up too.

My background is in applications development and I don't know much about Unix system administration, beyond the very basics.

What tools would I use to begin diagnosing this problem?

Is it possible that the server was hacked, and that there's some kind of Trojan horse or virus on it?

OPTIONS

       -h, --help

	      if specified, get connstring and slice defaults from the given Django settings module. Default: empty.

       -c CONNSTRING, --connstring=CONNSTRING
	      connection string to use. Default is 'Meta:tcp -h 127.0.0.1 -p 6502'.

       -s SLICE, --slice=SLICE
	      path to the slice file. Default is '/usr/share/slice/Murmur.ice'.

       -e ENCODING, --encoding=ENCODING
	      Character set arguments are encoded in. Default: Read from LANG env variable with fallback to UTF-8.
