Public bug reported:

As the title says, multiple SIGHUPs that are sent to the keepalived
process might cause it to forfeit mastership and re-negotiate a new
master (which might be the original master). This means that when, for
example, associating/disassociating 2 floatingips in quick succession
(each triggers a SIGHUP), the master node will forfeit re-election
(causing it to switch to BACKUP, thus removing all the remaining FIP's
IPs and severing connectivity.
