PHP Warning: mm create() failed

What errors are these and how it affect the website?

Hi there,

There is a folder under my website which is used to store only PHP files (All PHP files are used to redirect visitors to affiliate links). Everything goes well for the past year.

However,ever after I have changed my hosting, I encounter errors in that folders. The error log shows:-

[26-Nov-2009 18:17:49] PHP Warning: PHP Startup: mm_create(0, /session_mm_cgi2243) failed, err mm:core: failed to open semaphore file (Permission denied) in Unknown on line 0
[26-Nov-2009 18:23:29] PHP Warning: PHP Startup: mm_create(0, /session_mm_cgi2243) failed, err mm:core: failed to open semaphore file (Permission denied) in Unknown on line 0
[26-Nov-2009 18:23:53] PHP Warning: PHP Startup: mm_create(0, /session_mm_cgi2243) failed, err mm:core: failed to open semaphore file (Permission denied) in Unknown on line 0

I'm getting this error since day one in my new hosting on 2rd November. I wonder is this anything to do with my web hosting? And is this something I should worry of? (I have not seen any redirection problem with manual surfing)

For your information, the coding of my PHP files are:-

<?php ob_start(); header("Location: my-affiliate-links"); ?>

It seems that your browser did not direct you to the correct page. <br>
<a href="my-affiliate-links" target="_top">Please click here to continue.</a>

<?php ob_end_flush(); ?>

Please advice.

Yes, it certainly appears to be a server configuration issue and if your hosting provided has updated the server on the day the messages started appearing then indeed that is the cause. Warning errors are just that, warnings, but they could indeed effect the way your site operates and are always worth investigating and getting cleared up.

Thanks coopster! Yes I've contacted my hosting provider and they seems to know something. They are now checking things up and I'm waiting for their answer.

Exactly. Warning errors are uncertainty. We have no idea in what sense and what time it will affect the site operation.
