+ When setting a high amount of allowed simultaneous connections you will need to add and or increase the following two <b><a href='/system_advanced_sysctl.php'>'System Tunables'</a></b> kern.maxfiles and kern.maxfilesperproc.
+ For HAProxy alone set these to at least the number of allowed connections * 2 + 31. So for 100.000 connections these need to be 200.031 or more to avoid trouble, take into account that handles are also used by other processes when setting kern.maxfiles.
