700% CPU usage on server

Hello i recently checked the oxide logs and found that a plugin or config was causeing CPU to spike high every once and awhile i come here today to see if anyone know's this plugin from the error i got i thought it was RustIOFriendlistAPI but the version does not match then i assumed it could be RUSTIO live map but i do not see that plugin installed except for a configuration file any help would be appreciated to fix this issue.

Also the error spammed the log file over and over for atleast 5minutes

22:35 [Error] Failed to call hook 'OnPlayerChat' on plugin 'RustIO v2.9.0' (MissingFieldException: Field '.Arg.connection' not found.)

Limiting your server fps will also help, if updating Rust IO won't solve the issue. I usually use 128 or 256 as my max fps for my servers.

Code:

server.maxfps "128"

 

How about a real dedicated machine?

 

Wulf, why weapononback support dupe items? More servers use this plugin, but they dont know, what they server supports dupe items
