An application is getting the title error randomly. I have looked in the db2diag.log on both the web server where the application is running and on the db2 database server. I don't see anything in either file that indicates an error occurred. The application is registered an an ODBC application, using the IBM database driver. It is connecting to db2 7.1. Anyone have any ideas where to look next for a possible reason for the failure?
