ARP age effecting server redundancy

[GavenBP]

I have two Linux servers providing the same service via a virtual IP managed by Heartbeat.  My layer-3 switch is a 5406R.  The default 20 minute arp age setting makes failover almost worthless.  Shortening it to 1 minute solves that problem but it reminds me of the old joke about using a brick to kill a fly on the window.  Is there a way to keep the arp age at 20 minutes but instruct the switch that if an arp enrty becomes invalid inside that window to purge it immediately?
