Olivier Houchard 88698d966d MEDIUM: connections: Add a way to control the number of idling connections. ... As by default we add all keepalive connections to the idle pool, if we run into a pathological case, where all client don't do keepalive, but the server does, and haproxy is configured to only reuse "safe" connections, we will soon find ourself having lots of idling, unusable for new sessions, connections, while we won't have any file descriptors available to create new connections. To fix this, add 2 new global settings, "pool_low_ratio" and "pool_high_ratio". pool-low-fd-ratio is the % of fds we're allowed to use (against the maximum number of fds available to haproxy) before we stop adding connections to the idle pool, and destroy them instead. The default is 20. pool-high-fd-ratio is the % of fds we're allowed to use (against the maximum number of fds available to haproxy) before we start killing idling connection in the event we have to create a new outgoing connection, and no reuse is possible. The default is 25.		2019-04-18 19:52:03 +02:00
