Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

New problem: for some of my sites, I got FastCGI working. For some
sites not. PHP dumps a 200MB core file in /tmp. I think we really got a
crash here.

Ok, I've got something interesting. I've been digging through the
source and found the statement PHP_FCGI_MAX_REQUESTS. I've found the
file /sapi/cgi/README.FastCGI, which says some things about the
environment settings PHP_FCGI_CHILDREN and PHP_FCGI_MAX_REQUESTS. I'm
running PHP now with 5 children and everything looks oke (Don't close
this bugreport yet, please. Wanna do some more tests first). It even
survived several stresstests with 'ab'.
But now I have this question: Why is this important (read: necessary)
information NOT in the manualpage!?!?!

5.2.0RC5-dev also quits/crashes. I agree that Valgrind doesn't show any
crash. But the result is the same: PHP stops running. I'm trying real
hard to find out what is happing or what causes PHP to quit/crash. It
looks like it's random. Somethings it stops after 100 requests,
somethings after 5000.
I'm using Debian sarge, which comes with PHP 4.3.10. This version has
the same problem.
I'm writing my own webserver and I'm now implementing FastCGI support.
So, it is possible that my webserver doesn't send the right FastCGI
commands/record information. But if so, it shouldn't make PHP to stop
running.
