We can see in the logs that the serverload was normal until around 23:15:
...
10:50:03 PM 0 271 1.54 1.52 1.34
11:00:01 PM 11 228 1.20 2.02 1.87
11:10:01 PM 6 232 2.07 1.75 1.80
11:22:25 PM 0 712 46.38 55.42 34.00
Average: 4 213 1.48 1.55 1.38
...

Then it jumped up to over 55 which is very high - below 5 is normal. Over 60 and the server will go down.

I can see alot of processes like theese was running:
...

....

The above is just an example of at least 60 processes with the same name (misc.php) that was running at the same time.

But all looks ok now - so I guess it was Your script that couldn't handle to many visitors.

Can this be true? What to do to prevent it next time?
