Hello! I use HAProxy to load balance HTTP(S) traffic to some web servers. Web servers then connect to a database. I have noticed that when we restart the database some errors occur (and that is normal during the restart).
However the problem is that **a few hundreds connections remain open from HAProxy to the Puma web servers forever**. That slow down HAProxy. When we restart HAProxy then everything works fine again and the number of backend connections drops to zero, which is the normal value since we use option http-server-close. We have also configured the following timeouts but nothing has changed (some connections to backend remain open forever): timeout client 10s timeout client-fin 5s timeout http-request 5s timeout server 30s timeout server-fin 10s timeout connect 10s timeout queue 10s HAProxy Version: 2.0
