I created my phpMyadmin in Windows Azure which only allows 1 MySQL database for free users.

After creating a phpMyAdmin I linked MySQL Database Resources to another Website.

In this website I try to login my accounts registered to the database.

At first it goes smooth and seems there is no problem, but as i try to continue accessing the website which retrieves details from the linked MySQL Database Resources, The website returns and error of..

User 'b48a56f527c793' has exceeded the 'max_user_connections' resource (current value: 4)

But after a while 3-5mins the connection is good again.

At first I think the Windows Azure just tries to limit traffic but is it really that real cause of the problem or did i made mistake in setting up my phpMyAdmin in Windows Azure?

How to fix that error?

Big thanks in advance!

When you use MySQL on Azure you have to know is it provided by ClearDB, and the free tier is very limited. You can check the limitations here. For example you only have 4 concurrent connections limit, which is quite restrictive.

As a suggestion - never use mysql_pconnect in your scripts, but always use mysql_connect and always kill your connection when you don't need it anymore (i.e. when you retrieve the data).

I'm not 100% sure, but I think default installation of phpMyAdmin uses mysql_pconnect, which might keep idle connections as a resource from these 4 you have.

If you are using ClearDb on Azure which is the default option, ClearDb has really tight limit for simultaneous connections. Check it here:
