Database Errors Since 3.8 Upgrade
 

Hi,

Since upgrading to 3.8 last Saturday I have had many complaints that the forum is slow to load and I have now had the following error twenty times in the past three days.

How do I fix it:

Database error in vBulletin :

mysql_connect() [<a href='function.mysql-connect'>function.mysql-connect</a>]: User otpsoft_ already has more than 'max_user_connections' active connections
/home/otpsoft/public_html/buellersdownunder/includes/class_core.php on line 311

MySQL Error :

You will need to contact your host to raise the maximum number of connections

They have already upped the Apache "Max_Connections.
The above error is in the VB Database ........
Using the diagnostics tool in admincp shows that max_user_connections is set in the MySQL database at 30 ............................. how do I lift this limit ?

Your host will need to change the MySQL configuration.

I just went through this exact same thing. My hosting company was great in helping me figure this out, so ill pass it on :)

When your database gets errors it will create "overhead". A bit is ok, but I had 22 megs lol. When vBulletin makes a connection to your database, it should release it. When you have a lot of errors in the database, it locks or freezes connections forcing vBulletin to make another.

What I had to do was have the hosting company clear all those forzen/locked connections. Then do a repair/optimize on the database. And stay on top of it. I now do a repair daily just because. I'm also trying to track down what it is that is causing most of my errors. Add ons/plugins can do it, but you have to figure out which one is the culprit lol

30 connections should be more then enough for even a big forum. I was amazed how much faster the forum has been running after getting this all fixed.

Hope it helps

Did you turn off your forum before the upgrade? Sounds like you built up a bunch of errors while you were upgrading as mentioned above and now its clogging your system.

Just another note

My system was so clogged, I could not even run the database repair. I couldn't connect to it until the host company killed some of those connections.

I have a small forum, maybe 20-25 users on at once. My Max connections is set at 65. You can do the math on that one lol upping the max connections is a bandaid solution, you will have to find the cause first. I would start with getting it cleared out, optimize the database, then start searching the logs to see what errors are going on. I've noticed quite a few with our acrade, I may turn it off to see what happens. I've also seen quite a few with the 'search' button. I'm not sure yet what to do with that one.
