Description

dhcpd is restarted twice on the secondary system after every config sync. In at least some circumstance (ticket MPG-56559), it restarts 4 times on the secondary on each config sync. That may be specific to use of static ARP w/DHCP, haven't had a chance to fully test that theory.

Where running DHCP failover, which is most cases with config sync, restarting dhcpd multiple times back to back seems to occasionally cause both instances of dhcpd to get stuck in odd states that don't return to normal/normal. Keeping it to a single restart seems to be fine. Restart it several times in quick succession, and it breaks failover status.
