Just a simple though on health checks after a soft reload of HAProxy....

If for example you had several backend servers one of which had crashed...
Then you make make a configuration change to HAProxy and soft reload,
for instance adding a new backend server.

All the servers are instantly brought up and available for traffic
(including the crashed one).
So traffic will possibly be sent to a broken server...

Obviously its only a small problem as it is fixed as soon as the
health check actually runs...

But I was just wondering is their a way of saying don't bring up a
server until it passes a health check?
