I keep getting a MAX Connections DB error from a use thats not on my board.

So every day I get a bot trying to hack the site and Ive IP blocked with a wildcard * but still it says that this specific user has MAX Connections. Yet as the title states this user isnt part of my board. Im not really sure how to check the database to see if this guy someone gained access and is masking his id and actual IP. Any suggestions?

Check the plugins for any newly added ones, there could be code present in one of the plugins allowing some form of shell script access, or loading a file that allows such access.

You can use Securi to check the site, it does check forums a little better than other scanners:

Be sure to also run suspect file versions from the back-end under:
> Maintenance > Diagnostics > Suspect File Versions

You can go further and read the following guides as well to run other checks:

You can also change max connections in your server by editing the my.cnf file.. max_connections
