A large volume of request logs in our Unreal Engine Editer.

[Image Removed]Recently, several colleagues and I have suddenly encountered a large volume of request logs in our Unreal Engine Editer. These logs are flooding our work logs, making them difficult to track. Could you advise what these abnormal logs are and how we can disable them to avoid further disruption to our workflow?

Hi [mention removed]​,

That log is part of Unreal’s UDP messaging system. This is used to communicate and send messages between computers using the UDP protocol. These messages you see can be caused by multiple factors. Plugin liks Livelink or Remove Control use them to send information between the software and your computer.

If the engine does not recieve all parts of a message within a certain window (StaleReassemblyInterval property inside the UdpMessageProcessor), it consider the message stale and it discards it. This process is the one that triggers the message you are seeing.

This can happen by multiple causes. The sends could stop sending messages at mid-transmission by any reason, there could be a network congestion and many other reasons.

That message spam could be caused by something going wrong in your project, but if you can work totally normal, you can disable the logging by typing to the console:

Log LogUdpMessaging off

This would disable overall the logging of the UDP plugin. You can also set it directly to the DefaultEngine.ini if you don’t to write it every time you open the unreal editor:

[Core.Log] LogUdpMessaging=off

If you are sure the you are not using UDP Messaging at all, you can also disable it by going to ProjectSettings->Plugins->UdpMessaging and disable EnableTransport.

Inside the same tab, you also have StaticEndPoints. This are the ips in which the UDP plugin will be aware for communication. If there is any IP there that should not be listed be sure to remove it.

Let me know if any of these settings did the job or if the issue is still present. I also saw the Unreal 5.6 has done changes to that logging so it might be fixed in that version.

Best,

Joan
