Re: random errors

Hi Divak

PHP with dynamic fastcgi_pm doesn't work reliably. The main
problem is that SIGTERM  isn't caught by php. Please see here:

http://bugs.php.net/bug.php?id=36158

Despite that, you seam to have additional problems ontop of what's
described above.

You should also consider using a different version of mod_fastcgi.
This is the version I am using:

http://www.fastcgi.com/dist/mod_fastcgi-SNAP-0404142202.tar.gz

I hope this helps.
