XF 1.5 Server Errors


Active member
I'm getting a few server errors being logged in the admin section. Here's what they look like:

One says "User tjforum_admin has more than 'max_user_connections' active connections"

The next one says "Resource temporarily unavailable"

Not even sure where to start with these, so I'm hoping you guys might have an idea, or maybe you've seen this before?

The max connections is a limitation imposed by your host.

It could be that it is particularly low, or it could be due to some sort of DDoS/flooding, or an add-on causing it.

The second error is related to the same issue.

Got it. I've got a dedicated server so I may be able to fix this myself without calling up the hosting company.

Is this something that would be found in the php.ini file I assume?

Found it in WHM through the PHP Configuration editor settings. I changed it from 128 to 256. We will see if that fixes the issue.

As always, thanks for your prompt response, and your help!

Not sure.. but if it's a PHP option you changed, it won't effect it. That is a DB error from MySQL telling you that there are more connection attempts than the variable in my.cnf is configured for.
The variable is the max_connections one, and the my.cnf should either be located at /etc/my.cnf or /etc/mysql/my.cnf (typically).
This could be due to a lot of valid traffic, or a typical WordPress DDOS attack.
