2006    780     65000, currently. 

Last column is the max, what about the other two? Only the middle one changes when I start new processes.

It seems you might be right that the load climbed until the server stopped responding, and then the user asked for it to be restarted. But there's a whole hour unaccounted for, which I find odd.

Thank you all for the help,
