Query data overflow, Mods/Signatures will not be correctly received by clients. Remove unused mods or change your server configuration to allow for more data to be sent.

[[TL] OfficialMikeJ]

When I start my server. After it's fully started it get the following message:

 Query data overflow, Mods/Signatures will not be correctly received by clients. Remove unused mods or change your server configuration to allow for more data to be sent. 

I have added the following to the server.cfg:

 steamProtocolMaxDataSize = 1024; 

The above line in the server.cfg file does nothing. not sure which line is should go in ?.

Thanks.

I know I'm late, but you just add it to server.cfg and adjust the value until it resolves the issue, unless you're running like 400+ mods, then just ignore it, make a collection and link everyone as this only really affects clients joining outside of a group, with excessive mods..

The maximum MTU most things are configured for is "1500", and you have to also account for the overhead of TCP (8bytes), so the maximum usable would be "1492" for TCP however, if you use a VPN should adjust it to be lower e.g. "1420" to account for VPN overhead. A value of 1492 is the most you can send without fragmentation when using TCP that will split the packets up, and may cause issues for clients with older networking hardware.

While Arma 3 is using UDP for networking this will still limit your ability to send a large mod list., You should at most use "1460" You can force a value much higher, than 1500 (e.g. "8192" this allows a excessive large amount of mods) however this may harm some users by preventing them access to your server, depending on the network hardware and system hardware or configuration and ISP limitations.
