catastrophic failures with datasnap servers and dbexpress

[wloeppky]

Using D2007 with dbexpress. Just converted Delphi 7 project to Delphi 2007. Delphi 7 project was working properly. Now we are finding we are getting sporadic "catastrophic failures" while just doing pretty simple queries. These errors are com errors from the datasbap servers. Are there any known issues with the dbexpress driver that could be causing this since the failures are often just when executing pretty simple queries. Anything known that might cause a memory leak or AV error?

Thanks, Wayne

Please, specify the product name and the exact product version you are using to work with database.

Realized I should have posted to dbexpress drivers, but I am using dbexpsda40.dll version 4.25.9.

Could you send us a small test example that demonstrates this problem at dbxsda*devart*com? Also include script to create server objects and information about your SQL Server and client versions.

Found the issue is not in the driver, we switched in a different SQL Server db express driver and still have the same issue. Thanks for responding.
