Error Code 10040

Error code Error Code 10040 is a common Windows issue that typically arises from “A message sent on a datagram socket was larger than the internal message buffer or some other network limit or the buffer used to receive a datagram into was smaller than the datagram itself. [WSAEMSGSIZE (0x2738)]”.

Overview

In this article, we’ll focus on resolving the issue described as: “A message sent on a datagram socket was larger than the internal message buffer or some other network limit or the buffer used to receive a datagram into was smaller than the datagram itself. [WSAEMSGSIZE (0x2738)]”. This error, identified by the error code Error Code 10040, can impede your system’s performance, and here’s how you can fix it.

Identifying the Problem

Error Code 10040 occurs when a message sent or received over a datagram socket exceeds the maximum buffer size configured for the socket. This can happen due to several factors, including:

  • Misconfigured socket settings
  • Network configuration issues
  • Hardware limitations

Common Fixes

Several common fixes can resolve Error Code 10040:

  1. Check Socket Settings: Ensure that the socket buffer sizes are appropriately configured for the intended message sizes. You can adjust these settings using the setsockopt function.
  2. Review Network Configuration: Verify that the network settings, including firewall rules and port forwarding, do not restrict the message size.
