Multi-step OLE DB Operation Generated Errors
Today one page returned:

Error Executing Database Query.

Error Executing Database Query.
[Macromedia][SequeLink JDBC Driver]Network problem, session aborted due to internal error in remote procedure call, connection closed.

This was a problem being caused by the access jdbc driver. I changed the driver for your DSN to the default in ColdFusion 8 and that fixed the problem.
