max_user_connections error again and again. Does q2a close connections?

Wed, 10 Feb 2016 10:40:17 +0000

I am still not rid of this error, see also http://www.question2answer.org/qa/18513/already-max_user_connections-active-connections-include

PHP Warning: mysqli::mysqli(): (HY000/1203): User db348277_6 already has more than 'max_user_connections' active connections in /qa-include/qa-db.php on line 66

In the net I read:

"Your code is opening the connection to the database, but not closing it. Please see the following link for more help with properly opening and closing your database connections"

Could it be that q2a does not close the connections?

Note, I have no root access and cannot change the value of "max_user_connections". It is set to 35. This I found out by: "SHOW GLOBAL VARIABLES LIKE '%connections%'

- - -

My provider informed me that they will not increase this value on shared hosting, only on managed server which would cost me 100+ Euros :(

So I wonder if the "hack solution" on stackoverflow: http://stackoverflow.com/q/11183727/1066234 could be one way for us: Disable this error warning by @mysql_connect() ?

My server's error log says:

PHP Warning: mysql_connect() [<a href='function.mysql-connect'>function.mysql-connect</a>]: User db123456 already has more than 'max_user_connections' active connections in /qa-include/qa-db.php on line 66

This error appeared yesterday, 20-Oct-2012, from 18:50:17 to 18:51:01 (about 3 times per second), and 18:53:40 to 18:53:47 (about 3 times per second).

On stackoverflow they say it is "not a programming problem, just quantity of resources available".

But why haven't I got this error over the last 7 months?

Update 2012-12-14

My server logs showed me that a Chinese bot was going over a lot of tags, which obviously caused the error, here some lines:
