Amazon have probably removed the DNS after it's been offline for over a
certain period of time.

Hi,
I have a strange and random problem with Haproxy. Sometimes, I have an
error when I'm trying to reload the configuration file.
Reloading haproxy: haproxy[ALERT] 064/083311 (12629) : parsing
[/etc/haproxy/haproxy.cfg:314] : Unknown host in

[ALERT] 064/083311 (12629) : Error(s) found in configuration file :
/etc/haproxy/haproxy.cfg
In fact this host is unreachable because it's a server who has been
remove since 2 or 3 days. But I don't know why I have this error.
Normally Haproxy accepts any server in a backend even if he is down.
Each day we launch and remove server from a backend. We are in Amazon
AWS and we use the version 1.5 dev-7 of Haproxy.
This error appear only one time by month(approximately). I suspect too
long downtime who become unknown host but I'm not sure. Haproxy has
this mecanism?
Thanks in advance
Matthieu
