I ran an SVN command and my LAMP Crashed

I am running a VPS on debian sarge, its got LAMP, apache2, php5 to be exact.

mainly it is driving a wordpress blog.

So to take advantage of wordpress 2.5's subversion feature i wanted to install it on my site to do command line upgrades for future wordpress upgrades.

I had mysite in the following directory structure, /var/www/httpdocs/mysite/

I created a /tempblog/ directory in the site root folder like the directions say on the wordpress site @ the following url-

also once i created that folder, i thought i was following directions properly and i entered the following command:

Where I think I messed up was that i did not have subversion installed on my system.

So what happened after I ran that one command, nothing. and everything else pretty much crashed after that.

For all core Unix commands i get:

when I run ps aux I get :see attched img. link to screengrab: http://tinyurl.com/6gm5fg

My question is, is there any way to fix this and revive my site? or should I nuke and reinstall LAMP....i am clueless...

I have rebooted twice and still no life..

thanks for your help...
