How to fix “Too many open sockets. [WSAEMFILE (0x2728)]” – Error Code 10024


Error Code 10024

Error code Error Code 10024 is a common Windows issue that typically arises from “Too many open sockets. [WSAEMFILE (0x2728)]”.


In this article, we’ll delve into the details of resolving Error Code 10024 in Windows, which manifests as “Too many open sockets. [WSAEMFILE (0x2728)].” We’ll explore its causes, symptoms, and effective solutions.

Identifying the Problem

Error Code 10024 occurs when a system’s maximum number of allowed open sockets is exceeded. This can happen due to excessive network activity, such as a surge in client connections or a faulty application creating a large number of unnecessary sockets. The primary symptom of this error is network connectivity issues, causing applications that rely on sockets to malfunction or fail.

Common Fixes

1. Close Unnecessary Processes:
Identify and close any applications or services that are not actively being used. These processes may be consuming sockets in the background.

2. Reboot the System:
Restarting the system can terminate all active processes, freeing up sockets and potentially resolving the issue.

3. Adjust Socket Limits:
Increase the maximum number of allowed sockets by modifying the registry value “MaxUserPort” located at “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters.”

4. Check Network Adapters:
Ensure all network adapters are properly installed and functioning. Defective adapters can cause socket issues.

Advanced Troubleshooting

1. Reset Network Stack:
Use the command “netsh winsock reset” to reset the network stack and potentially resolve socket-related problems.

2. Disable IPv6:
Temporarily disable IPv6 by opening “Network and Sharing Center” and unchecking the “Internet Protocol Version 6 (TCP/IPv6)” box. This can resolve issues specific to IPv6.

3. Change IP Configuration:
Assign static IP addresses to network adapters instead of relying on DHCP to streamline socket management.


By following the solutions outlined above, you can resolve Error Code 10024 effectively. Additionally, monitoring network activity and optimizing socket usage can help prevent this error in the future. Maintaining the integrity and efficiency of your system is paramount to ensuring uninterrupted operations.
