>There's still the option I suggested a while ago - give each connection a GUID when it's created and look for cases where the same connection is used by more than one hit?

I have eliminated the fact that this could be caused by reserved words. I adjusted for most of the places where that applied. But, this was not the source of the problem. I ran a stress test tonight by launching four simultaneous processes against the server at every second. The result was a total disaster. I got about 26 errors per minute. It is always the same types of errors. Here is the list of the types of erros:

Command contains unrecognized phrase/keyword.
SQL: Column 'FieldNameHere' is not found.
Function name is missing ).
Index does not match the table. Delete the index...
Variable 'FieldNameHere' is not found.
Syntax error.

I will run the application by creating the application object at every hit. I need to know if that could be a factor.
