anyone have any good resources for understanding the basics of all of this?

#52Earlier quoted context omitted.
Someone set us up the (fork)bomb. That didn't take long. Sadly it's a bit silly and ruins all the fun for the rest of us :-/
Could something like this ( http://www.cyberciti.biz/tips/linux-limiting-user-process.ht... ) be quickly implemented on the server?
Yep, that's why you're seeing that error message rather than the machine immediately grinding to a halt!
(Please don't forkbomb it, though.)

#55Someone already fork-bombed it ;-)

#56Aw, sad. The server seems to be non-responsive.

#57It looks like the machine is under heavy load. My shell just stopping responding and now ssh hangs while connecting :-(.

I am. I think their server must be overloaded. I bookmarked the blog post announcing this and I'm going to try again tomorrow.

I was in there 5 minutes ago, did cat /levels/level02.c and then it stopped responding. I don't think cat could crash the server, but if it did, I'm sorry?

#60Bah. Looks like the server is now not responding. Bummer, because this is really fun.
