It is indeed the same bug as the one I described: my logs were the same
as yours when I was using the php forking feature.
As far as I remember, the child php processes were dropped by the
parent php process (acting as a dispatcher) because apache's fastcgi
process manager "Fastcgi PM" sent a SIGKILL signal to it (the only PID
the fastcgi PM is aware of because it spawned it). This signal is
normally only sent if the process do not exit a few seconds after being
sent a SIGTERM signal. The problem is not the parent being killed, but
the children waiting on their own loop infinitely.
I guess this bug is in the fastcgi accept loop, which leaves the php
children stalled waiting on a FD without any process attached to the
other side.

I still experience this on Ubuntu Hardy,
PHP 5.2.4-2ubuntu5 with Suhosin-Patch 0.9.6.2 (cgi-fcgi), so this
should be reopened.

Workaround: Kill those lurking process regularily using a cronjob.
This works for me (Ubuntu Dapper, PHP 5.1.2 (cgi-fcgi) (built: Jul 17
2007 17:21:59) ), you probably need pkill -9 .
#/bin/bash
pkill -f -x /usr/lib/cgi-bin/php -P 1

The problem is that this bug affects Debian's PHP5 package of etch[1]
and in order to fix it the right patch is required. We can't simply
'update' the source package.
