In this blog post, let’s learn about the error message “4014 – A fatal error occurred while reading the input stream from the network. The session will be terminated (input error: %d, output error: %d).” in Microsoft SQL Server, the reason why it appears and the solution to fix it.
SQL Server Error Message
4014 – A fatal error occurred while reading the input stream from the network. The session will be terminated (input error: %d, output error: %d).
Reason for the Error
The SQL Server error message 4014 typically indicates a network-related issue that has caused the server to terminate the current client connection. This error can be caused by a variety of factors, including network connectivity problems, hardware issues, or problems with the client driver. Some possible causes of the error include:
- Network connectivity problems: The error can be caused by network connectivity problems, such as a slow or unreliable network connection, which can cause packets to be dropped or delayed, leading to errors.
- Hardware issues: Hardware issues, such as a faulty network adapter, can cause the error to occur.
- Problems with the client driver: The error can also be caused by problems with the client driver used to connect to SQL Server.
Solution
Here are some examples of how to fix the error:
Example 1: If the error is caused by network connectivity problems, you can try to optimize the network and check the network hardware. You can also try to increase the network packet size to prevent dropped packets.
Example 2: If the error is caused by a problem with the client driver, you can try updating the driver to the latest version. For example, if you are using the ODBC driver, you can download the latest version of the driver from the Microsoft website.
Example 3: If the error is caused by hardware issues, you can check the hardware of the server and the client machine. You can try replacing the network adapter or other hardware that may be causing the problem.
Overall, it is important to troubleshoot the cause of the error in order to find the most appropriate solution.
