That's very odd considering I have several Windows 2003 servers all running CF8. These servers host about 200 different websites using CF8 that ALL connect to a separate dedicated MySQL server. Some of the sites connect to a MySQL 4.x service and others MySQL 5.x. All of these sites connect via the provided MySQL 4/5 driver in the CF Admin.
The "Maintain connections across client requests" is apparently a default option as this is set on all of my datasources. Perhaps this is why I never see this problem. So, as I have many sites accessing a single database server all with this option configured... where is the problem with this? I don't see any real "performance impact" because of this option being checked. ???

The database is simple and I can make the change quickly. To wrap this up, based on what I've learned and what my web research shows: * The problem exists only for MySQL with ColdFusion running under Windows * If you turn off Maintain Connections across client connections in the advanced datasource settings, the problem goes away. Obviously this would impact server performance and isn't a fix. * So, it is sort of a communications problem. It seems that between ColdFusion and the MySQL driver the reference to the database connection gets confused. ColdFusion expects the connection to the database, but doesn't find it and throws the error. * Maybe there's a set of ColdFusion/MySQL/Server configuration settings that will fix this. Or, maybe it's a ColdFusion or MySQL bug. I just don't know. Anyway, thanks for all the great ideas. At least I learned some new tricks!
