Description Ruslan Lutsenko 2012-07-06 17:26:01 UTC

It seem I hit same bug as on https://bugzilla.redhat.com/show_bug.cgi?id=768119

Description of problem:

Removing a real server from a virtual server in keepalived.conf and then reloading (eg. service keepalived reload) does not remove that real server from ipvs tables.

keepalived --version
Keepalived v1.2.2 (06/25,2012)
