Hello,
In server.c on line 2912
I believe the server state file is unsigned long and when loaded back its
being compared with USHRT_MAX
In my own development environment I had commented the following if
statement, as server state is fully controlled by the haproxy.... and
everything was working fine. But since this isn't the "Real" fix Ii assume
there will be needed of some kind of conversion to have a valid comparison.
```
if (port > USHRT_MAX) {
chunk_appendf(msg, ", invalid srv_port value '%s'", port_str);
port_str = NULL;
```
