PHP Script not shutting down? Or some other bug making it spawn lots of procs

Hello,

I am really desperate here. Dedicated host with tens of thousands of users of the site crashing periodically. If you can solve this I will love you forever.

My hosting povider instructed me to run the SSH command ‘ps uaxf ‘ to demonstrate that there are many instances of a single php script running and ‘free -m’ that the server is getting too low on memory.

I am new to having my own dedicated box so I’m terribly confused. They are telling me that this output means that the PHP script in question, import_photo.php, is not terminating properly. I can’t see how this could be, I have used set_time_limit(), checked for infinite loops etc, there are no database connections made, etc.

For the ps uaxf output… I am a new user and cannot do a pastebin, so here’s a sample line that is repeated a lot:

[CODE]

And the PHP Source for the import_photo.php:

set_time_limit(20);

Finally, free memory looks like this

My host has stated:
[I][INDENT]Your server had quite a bit of iowait just before it became unresponsive. It looks like there was quite a bit of php processes with this one having 392 instances:

/usr/bin/php /home/zane/public_html/startgoogleplus/api/import_photo.php

Please let us know if we may further assist you.[/INDENT][/I]

On a (possibly) related note…
I upgraded from a shared to a dedicated hosting package days ago, which involved repointing the nameservers of the domain of course. It worked fine after a bit, but for the last 18 hours since this started my computer is connecting to the old nameservers and thus the old host again! Others do not seem to be having this problem, just me… but it is making testing damn near impossible!
The domain is StartGooglePlus.com
Old NSs are ns615.hostgator.com / ns616.hostgator.com
New NSs are ns1.inZania.com / ns2.inZania.com
