failed to open stream: Too many open files in ???

Hello guys,

I have a customer that there site keeps showing this error message

Warning: main(includes/languages/english/whos_online.php) [function.main]: failed to open stream: Too many open files in /usr/local/4admin/apache/vhosts/OURDOMAIN.com/httpdocs/includes/languages/english.php on line 682
This message shows up 3 times on the page then it follows up with the following message then dies?
Fatal error: main() [function.require]: Failed opening required 'includes/languages/english/whos_online.php' (include_path='.:/usr/local/4admin/apache/lib/php') in /usr/local/4admin/apache/vhosts/OURDOMAIN.com/httpdocs/includes/languages/english.php on line 682

I'm guessing this has something to do with Ty Package Tracker, as the site was working great until my clinet trid to use this addon for the fist time. If you refresh the website like 3 or 4 times the message will go away.

Any ideas on how to fix this?

Now when you try and check out the customer gets this message and then dies.

Ok I just got off the phone with my client, they where saying the noticed that the message started about the same time they hit 500 products.

You could try applying the fix from this thread ... I believe the attachments are at the end of it.
