Hmmm?  Your subject line says prefork.  With prefork, there are
no threads.  Anyway, no matter.

Stupid me. This happens when having developers crying in your ear all the time ;)

You should get cores from a segfault.  Have you enabled them?
(See Coredumpdirectory, and check limitations imposed by your
operating system and shell).

I enabled CoreDumpDirectory in httpd.conf, made a "ulimit -c unlimited" and started Apache. When I had a segfault there was no corefile in the specified directory and Apache was still running. Only the forked process was gone and a new was spawned. After two days or sometimes a week Apache gets really slow and can handle only a fourth or less of it's usual traffic.

We recently (for 2.2.9) fixed a bug that fits that description:
http://issues.apache.org/bugzilla/show_bug.cgi?id=44402
But that's not relevant to prefork.

Currently the page is not reachable.

Um, sounds like a problem in the network, below the level of apache.

I'm looking into this too.

PHP is always a prime suspect for this kind of problem.
If you're using mod_php, make sure you really are running prefork,
as PHP+threads is a classic recipe for random segfaults.

*lol*

Contradictory information is more of a problem.

I do my best.
