Intermittent mysql problems on PHP/IIS

[forcer]

Guys,

I have a serious problem on my Wordpress websites. I have moved the blogs recently from a different server and also upgraded to a newer version of mySQL and PHP. Its been 2 weeks now and the problem appeared for the 2nd time now.

What happens:

Suddenly, website stops working and wordpress reports:
Your PHP installation appears to be missing the MySQL which is required for WordPress" IIS sometimes

I have found out via phpinfo() that it really looks like that mySQL connector is unloaded. That is really strange as mysql is properly configured in php.ini

I think that possibly the IIS worker has recycled and after the recycling the mySQL extension didn't load up properly, because if I restart the IIS then websites are working again properly.

Do you have any advice how to fix it? Why mysql extensions are unloading?

Thanks!

newer version of mySQL and PHP could be your problem.
You should contact your server host and tell them your problem and they will help rather than loose costom.cos you can find hosting with the same versions that your site or scripts run on corectly.

I'm sure the problem is at your server. Check it with the hosting providers.

Thanks guys. I am escalating it, but not really hoping to get this sorted as it seems quite a specific problem.

If anyone else has any advice , then it would be appreciated.
