WSAEPROCLIM - 10067 (0x2753)
A Windows Sockets implementation may have a limit on the number of applications that may use it simultaneously.
Updated: Feb 21, 2026
Technical Meaning
The WSAEPROCLIM error code, represented by the numeric value 10067 or hexadecimal 0x2753, is returned when a Windows Sockets implementation encounters a limit on the number of applications that may use it simultaneously. This limit can be related to system resources such as file descriptors, network connections, or other internal mechanisms managed by the Windows Sockets provider.
Error Details
This error typically occurs in scenarios where an application attempts to create more sockets than the implementation allows at a given time. The exact limit is implementation-specific and may vary depending on the version of Windows and the specific Windows Sockets provider being used.
Usage Context
The WSAEPROCLIM error can be encountered when performing operations that require socket creation, such as establishing network connections or setting up server sockets for listening. It is important to note that this limit is not a global system-wide limit but rather a per-implementation limit managed by the Windows Sockets provider.
Developer Interpretation
Developers should interpret WSAEPROCLIM as an indication that their application has attempted to exceed the number of simultaneous socket connections or operations allowed by the current implementation. This error does not necessarily imply a failure in the underlying system but rather a limitation imposed by the Windows Sockets provider.
Related Errors
- WSAEMFILE: Indicates that the maximum number of file descriptors has been reached, which could be related to
WSAEPROCLIMif sockets are implemented using file descriptors. - WSAEADDRINUSE: Occurs when an attempt is made to bind a socket to an address and port that are already in use by another application or process.
FAQ
Q: What does the WSAEPROCLIM error mean?
A: The WSAEPROCLIM error indicates that the number of applications using Windows Sockets simultaneously has reached its limit, preventing further socket creation.
Q: How can I resolve this issue?
A: Review your application's socket usage and ensure it does not exceed the allowed limit. If necessary, optimize your code to reuse sockets or manage connections more efficiently.
Summary
The WSAEPROCLIM error is a specific technical limitation imposed by Windows Sockets implementations. Developers should be aware of this potential issue when designing applications that rely on socket operations and take steps to ensure they do not exceed the allowed number of simultaneous connections. Understanding this limit can help in optimizing application performance and avoiding unexpected behavior.
