Radim Vansa commented on ISPN-8902:
-----------------------------------

[~galder.zamarreno] It's not related to KQueue but your system configuration in general. Notice that when the test attempts to connect to 127.0.0.1 it gets refused immediately, when you try to connect to 127.0.0.[2-4] you're getting "Connection timed out" - I got these refused right away. When I run

{code}
08:44:54 at rvansa infinispan$ ip route show table local
...
local 127.0.0.0/8 dev lo proto kernel scope host src 127.0.0.1 
local 127.0.0.1 dev lo proto kernel scope host src 127.0.0.1
{code}

So I recommend adding similar route. Regarding 'real' IPs that don't respond quickly: how would you like handle this? You can always lower your connection timeout... I could imagine having a 'soft' limit that would trigger connection to another server (but not fail the previous connection attempt) but that would be an enhancement, not a bug fix.
