Wow Yann,
Thanks so much for taking the time.

I really meant "Is my approach incorrect?" Trying to mean It is
logical to assume things wrongly at first approach to a subject.

I applied the patch and I'm already testing it.
In a given configuration like:
BalancerMember http://ip1:7009/ hcmethod=GET hcuri=/ping hcpasses=1
hcfails=1 hcinterval=5 timeout=5 retry=30
BalancerMember http://ip2:7009/ hcmethod=GET hcuri=/ping hcpasses=1
hcfails=1 hcinterval=5 timeout=5 retry=30
--
The backend ip2:7009 always takes 6 seconds to reply to /ping uri for
testing purposes.
$ time curl -vk "http://ip2:7009/sites/ping";
...
< HTTP/1.1 200 OK
...
* Connection #0 to host ip2 left intact
* Closing connection #0
{"response":{"name":"testAlive.owcs","time":6.006}}
real 0m6.057s
user 0m0.007s
sys 0m0.002s
With the patch applied I seem to see mod_health_hcheck saying that it
is disabling the worker ip2 "sometimes" but not constantly, in a lapse
of about 1 hour I've seen the message just 8 times:
[Tue Apr 27 11:12:38.396687 2021] [proxy_hcheck:info] [pid 28713:tid
140079122761472] AH03303: Health check DISABLING http://ip2:port/
Since the backend ip2 is configured to respond in 6 seconds all the
times to that /ping URI (not the rest of normal uri). So
mod_proxy_hcheck should be disabling this worker constantly. Am I
correct?
If you need more information or some specific logging do not hesitate to ask.
Cheers
