Hi All  PHP + mod_fcgi users

FYI:

I already reported this a few month ago, but I wasn't really able to fix 
the problem.
Reducing the number of PHP children to 1 helped a little, but the
core of the problem wasn't solved.

mod_fcgi (fcgi_pm) kills dynamic processes using SIGTERM even
if they a in the middle of performing a request. PHP does not catch
this signal and fcgi_pm finally removes the process. The chance that this
happens seam to be small and it depends on the load, but it happens! You get
the "incomplete header" failure as well as a HTTP 500 in the access log.

For all of you who run php on mod_fcgi, please have a look at this:
