I´ve never heardabout this errors...

I´m Supportmanager from YaBB SE! We have about 3000 User using our software! And we have an integraded optimizing tool, what i wrote! also with db´s bigger as 50 mb or even 100 mb we run never in trouble!

Feel free to use it!

Btw: i think the trouble starts when you converts ISAM to MyISAM Tables and then starts optimizing...
