php5.fcgi looks like:
#!/bin/bash
ulimit -t 60
ulimit -u 100
PHPRC=$PWD/../etc/php5
export PHPRC
umask 022
export PHP_FCGI_CHILDREN
SCRIPT_FILENAME=$PATH_TRANSLATED
export SCRIPT_FILENAME
/usr/bin/php-cgi

These happen randomly, works hundreds of times, could be on one product, could be in another, doesn't seem to matter, as long as it is PHP code.
I think the key line was that /usr/bin/php-cgi was killed, the question is why is this happening?
