Error 500 When Load Is High. Anybody Else?

[W13]

I've noticed that when we start hitting and going past the 1 million posts mark, we begin to see tons of Error 500 "Internal Server Error"s.

I have to go and restart Lighttpd to bring the forums back online again.

What's odd is that page-generation time is less than 0.1 sec all this time... it's not like the server shouldn't be able to handle it. It just peaks really fast.

Anybody else this happens to?

Have you tried tweaking apache or mysql?

Sounds like he's using lighttpd, not Apache.

Unfortunately I'm not too familiar with lighttpd - perhaps there is a setting in it that caps the load you need to increase?
