Never got such a problem, but actually patched pulse for ARP issues when
using LVS, not FOS.

Can you run "tcpdump -n -i any arp" from the backup node while doing
manual failover and send us the result ?

Just willing to make sure pulse is actually sending ARPs. I'm asking
because people (on this list and also on lvs mailing list) reported
problems of this kind, which actually were problems generated by routers
caching arp entries or needing both ARP queries and replies.

Also, start pulse verbosely (pulse -v -c /etc/sysconfig/ha/lvs.cf) and
watch the logs to make sure you get "gratuitous fos arps finished".
