Hello, in src/lib/event.c there is: #define FR_EV_MAX_FDS (512) To my understanding, this limits the number of sockets FreeRADIUS can listen on, as each of those uses a file descriptor. Is there a specific reason for the number 512? I.e. is it worth trying to up it to my liking, or has this been tried before and fails? And, related: if I listen on IPv4 and IPv6 with ipv4addr and ipv6addr, this typically consumes two FDs. Can I have one listen statement with the ipaddr statement which then covers both (maybe the :: address), and does that consume only one FD then?
