Aruba Instant SSID arp table on cisco router filling up.

We have an Aruba Instant setup with a production SSID.  Layer 3 for the SSID lives on a cisco router.  While we only have 3-4 users authenticating on the SSID (via radius), we have been noticing the Cisco router arp table filling up the entire /24 address range.  The arp table appears to have 1 mac address associated with several IP addresses in the arp table.  We're running

Version:
6.2.0.0-3.2.0.3_37632 on the instant AP's. 
 
Has anyone else seen this problem before?  If a users tries to connect to the SSID and fails authentication, that shouldn't create an arp entry on the router should it?

Who owns that MAC?  ALso, I would recommend a code upgrade as well...

Re: Aruba Instant SSID arp table on cisco router filling up.

The MAC during the last instance was from a macbook pro.  After clearing the arp table and rebooting the AP with the active Virtual controller, everything started working again.  But this is the 2nd time we've had to do this.  I'll try upgrading the code as the next step.
