Haproxy resolvers accepted_payload_size

[ssteffen]

Hello,

we have pfsense with haproxy and try to resolve the backend adresses, like this https://www.haproxy.com/documentation/haproxy-configuration-tutorials/dns-resolution/

this works, however, there seems to be no way to increase the accepted_payload_size
which means, you can only have two or three backend servers. more than that and the dns server response is too large.

Is there any way to increase accepted_payload_size ?
