Insert Query status

I've created a web service to perform an insert query on a single table in mysql. However, there is no return on the query result. (seems to work fine in sql server?) One of the applications that consumes this insert query web service cycles through 600 - 1000 records and calls the insert service for each record. The max amount of records that get inserted are between 350-380. I can't find a way to see where the inserts fail. The SOAP Trader shows the proper amount of incoming messages received but gives no status on the success of the insert. Is there any type of limitation on the number of service calls that can be made? Is there any way to find out where the service calls cease to be processed?
