Too many MySQL connection Error

[j1mmy]

I'm sure many of you have come across an email error which says something along the lines of too many SQL connections etc.

I put Forward the error to my host and this is what I got:

These sort of errors usually happen when your web script has made too many connections to the MySQL server without enough disconnections hence the "too many connections" message -- mysql_connect() [<a href='function.mysql-connect'>function.mysql-connect</a>]: Too many connections.

This can be prevented by turning off what is called "persistent connections". This setting can likely be found in the configuration file for your vBulletin or in the admin panel. You may want too see if this is enabled, then disable it and see if it resolves these error messages.

Where can I find the connection configuration that he mentioned?

Look in your config.php file which is in your includes directory.

I have made changes to the config file, but I am still getting these messages?

Does this mean that sometime whenever someone is browsing the website they would come up with a 404 or something similar??

[Paul M]

Nope, they would get a database error page.

So when I actually disable the persistent connections via the config file, what actually happens to the MySQL connections? How does this affect it?

[ChopSuey]

The error tells you to disable it and see if it solves the problem.

Well, now I am getting this issue:

Database error in vBulletin 3.8.4:
