Proxy state attribute in accounting

Hello Community, I am doing store and proxy accounting to different servers, Now I want to remove the proxy-state attribute from the proxied packet. The problem is that other accounting servers that are not FreeRadius are not accepting proxy-state attribute. So they are not sending the acccounting response back. This makes the detail file size increase. I am using FreeRadius version 2.1.10 with roubust-accounting configuration. the proxy servers are being load-balanced. and detail file is being created correctly Thank you Waqas Toor
