How to fix “A blocking operation was interrupted by a call to WSACancelBlockingCall. [WSAEINTR (0x2714)]” – Error Code 10004

Overview

In this article, we’ll focus on resolving the issue described as: “A blocking operation was interrupted by a call to WSACancelBlockingCall. [WSAEINTR (0x2714)]”. This error, identified by the error code Error Code 10004, can impede your system’s performance, and here’s how you can fix it.

Identifying the Problem

Error Code Description:

Error Code 10004 is a Winsock API error indicating that a blocking network operation was interrupted by the WSACancelBlockingCall function. This error typically occurs when a thread terminates or exits while a blocking operation is still in progress, causing the operation to be canceled and returning WSAEINTR.

Common Scenarios:

• Thread termination or exit during socket operations
• Antivirus software interfering with network operations
• Firewall blocking network connections
• Network adapter issues or driver problems

Common Fixes

1. Ensure Proper Thread Handling:

• Verify that all threads performing socket operations are terminated gracefully.
• Use synchronization mechanisms to prevent premature thread exits.

2. Check Antivirus and Firewall Settings:

• Disable or configure antivirus software to exclude network operations.
• Ensure firewall rules allow connections from the affected application.

3. Reinstall Network Adapters:

• Uninstall and reinstall network adapters to resolve any driver issues or hardware problems.
• Update network drivers to the latest version.

4. Identify and Resolve Network Issues:

• Check physical cables and connections for any loose or damaged components.
• Contact your ISP if there are any network outages or connectivity problems.

Advanced Troubleshooting

1. Use Debugging Tools:

• Enable kernel debugging to capture trace logs and identify the thread that triggers the error.
• Use network monitoring tools to analyze network traffic and identify any anomalies.

2. Modify Registry Settings:

• Edit the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa and set the value of “MaxPoolThread” to a higher number (e.g., 2000). This allows for more concurrent kernel threads, potentially resolving the error.

Conclusion

By following the solutions outlined in this article, you can effectively fix Error Code 10004 and restore the proper functioning of your system. To prevent this error in the future, ensure proper thread handling, configure antivirus and firewall settings appropriately, and maintain up-to-date network drivers.
