VFP: The C0000006 Error and Troubleshooting Suggestions


You have an application written in Visual FoxPro. The application may terminate and close after reporting the following error:

ExceptionCode: C0000006 (In-page I/O error).


A C0000006 error is a networking or network connectivity error. Specifically, a C0000006 error is an in page I/O error. This error occurs when an application loses its underlying network connectivity.


Since a C0000006 error indicates a networking problem, the best option is to obtain a network trace and analyze the results. This normally involves opening a case with our Windows Platforms Support group to help you obtain the trace and interpret the results. 

While a C0000006 error indicates an underlying network problem, there are some suggestions you can try that might help prevent this error.
