0xC0000005 Access Violation exception when using ODBC driver
Operating system version
Windows Server 2003
Description of the issue
We have a web page that queries an FM table with an SQL SELECT query and lists records on the page. The page is left open on the computer and has a meta tag to refresh it every 60 seconds.
We use the ODBC driver provided with the installation in xDBC folder.
After operating normally for a few days, the application will start failing.
None of the queries to FM, even from different applications will work after this exception, although the web server will server web requests normally.
We have to restart the aspnet_wp process to make it work again.
