This is a problem much probabaly related to your mysql version, which is conflicting to the connector/j version.

Which mysql version are you using? Do you have any different connector/j? (other than the one that comes with JForum)

rapaz... meu ingres naum me permitiu entender muito ehehehe
well... let's see...
i changed de property "database.connection.implementation=net.jforum.PooledConnection" to "database.connection.implementation=net.jforum.SimpleConnection", because the variable "wait-timeout" is 15 and cannot be changed in the web server. And the version of mysql is 3.23.58.
Thanks!
