When running Unreal Engine 5.7.3 (Windows) on more than 60 machines on the same network, memory usage exceeds 90%.

We are experiencing an issue when launching Unreal Engine 5.7.3 on a large number of client PCs within an Active Directory environment.

When 60 or more clients launch Unreal Engine 5.7.3 simultaneously, the following behavior occurs:

The memory usage on each client suddenly increases to 95% or higher, causing Unreal Engine to freeze.

Just before the memory spike, the network usage reaches 100%.

All clients are on the same network segment.

When launching around 45 clients, the issue does not occur and everything works normally.

Is this a known issue when running Unreal Engine 5.7.3 on many machines within the same network segment?
If there are any recommended network configurations or workarounds, we would greatly appreciate your guidance.
