In ColdFusion 8.1 and later when working with a MySQL database some users may experience the following errors:

CF Error: null null
The error occurred on line -1.

At this time all MySQL DSN's are created with a default of Maintain connections enabled for proper management of connections between the servers. We have found that by removing this setting for the specific DSN experiencing the issue will resolve this.

To have this removed please contact our support department via chat, email or phone. Provide them with your domain name and the name of the DSN you are specifying and they will make this setting change within ColdFusion for you.
