Sun OS virtual zone ASA5520 arp problem

[Steve Whitson <swhitson () CCA EDU>]

I am using virtual zones on Sun OS and experiencing intermittent Mac
address table problem where two arp responses are being seen with the
same IP address causing an intermittent Mac IP mismatch and resultant
connectivity problem. As the table updates dynamically the Mac address
of the ASA 5520 outside interface is sometimes being seen as the Mac
address of the virtual zone for the server instance instead of the
Mac/IP for the zone. The Virtual zones are all in our DMZ interface. Has
anyone experienced this problem ?
