Do you use include directives? Maybe you've got infinite recusive include?

Doesn't seem so.

Using lsfo command, I'm getting this :
keepalive 1697 root 11u netlink 0t0 67899 ROUTE

and so on. Each reload creates a new one.

Which version of keepalived do you use?

from keepalived.

Keepalived for Linux - Version 1.2.13 - May 13, 2014

from keepalived.

I don't have such unclosed sockets on my installation using 1.2.13 doing HUPs too.

You've got netlink opened sockets which are created from within libipvs (compiled into keepalived) which in turn uses libnl1 (as a shared lib). Is it possible that this lib is outdated, or testing/unstable in contrast?

from keepalived.

Agreed with Alexey... I am not able to reproduce it here, performing a bunch of reload with HUP, everything is ok...
