Operating System: Linux 2.6.2 /Fedora Core 1,
PHP Version: 4.3.4
New Comment:
Quick explanation.
1. Parent Program, grabs a list of 25 domains, and then spawns off 25
children to process the domain. The parent does a mysql get lock on
the domain, and once the child process is done, it tells mysql to
release the lock which tells the parent the child is finished. Once
all 25 domains are finished the parent spawns a new instance of itself
and the original parent exits.
2. The child programs in certain cases can spawn children of their
own, but never more than 1 or 2 children. This keeps the code small
and effecient.
Hope this makes sense.

What does that new program that spawns these children do? Is it a long
living process?

Description:
------------
We started using a new program that spawns additional CLI php scripts
recently. And today, we started getting stuff like this:
PHP Warning: system(): Unable to fork [/usr/bin/php
/www/htdocs/onetime/spawn_domain.php 'businesslicensing.com' >
/dev/null &] in /www/htdocs/onetime/spawn_domain_parent.php on line 39
Now if I wait a few minutes, and restart the parent it will normally go
on about it's business. But then after a while it will all of a sudden
no longer be able to spawn new children.
All of the other bugs mentioned like this are based on Windows, but
this is a Linux box.
Reproduce code:
---------------
system("/usr/bin/php /www/htdocs/onetime/spawn_domain.php
'$db[domain]' > /dev/null &");
Expected result:
----------------
It should spawn a child CLI program and run.
Actual result:
--------------
It runs the code mentioned above.
