Hello - I'm attempting to use HAProxy's service discovery (SRV records)
along with `load-server-state-from-file` but the port numbers from `show
servers state` are incorrect.
Here is my example (HA-Proxy version 1.9-dev2 2018/09/12)
DNS configuration:
$ dig SRV _nginx._tcp.alpha.int
;; ANSWER SECTION:
_nginx._tcp.alpha.int. 18 IN SRV 1 1 32772
56b9c088-9bc5-4466-99af-ebebd3550791._nginx._tcp.alpha.int.
_nginx._tcp.alpha.int. 18 IN SRV 1 1 32773
c6032796-8c7a-4d78-8934-d98900c18383._nginx._tcp.alpha.int.

_nginx._tcp.alpha.int
As you can see, the port number in the SRV records are:
32772
32773
However, the srv_port value from `show servers state` is:
4294934532
4294934533
This causes the following error when haproxy attempts to read the state
file:
[WARNING] 261/162616 (1) : server-state application failed for server
'b1/www1', invalid srv_port value '4294934532'
[WARNING] 261/162616 (1) : server-state application failed for server
'b1/www2', invalid srv_port value '4294934533'
Can anyone help me out?
Thanks,
Pete
