ODBC Error After Multiple Connections and Disconnections
This article was previously published under Q154496 SYMPTOMS
When you are running ODBC applications using Microsoft ODBC drivers, you
may receive the following error message:
General error Failed to get the expression service CAUSE
This error can occur if ODBC applications connect to and disconnect from
the server repeatedly (over 50-60 times).
An example of such an application may be an Internet Web server applica- tion that is publishing ODBC data. For each Web-page-based query, the Web server may be opening a connection to the ODBC data source, processing the query, and then disconnecting from the data source. STATUS
