CISCO ARP PROBLEM
I currently have a 7604 that every 4 hours when the ARP cache clears my network looses connectivity for 8 minutes and then the table starts to populate once again.

what is the entire firmware version that you are referring too.
Sorry, wrong information. I forgot this is a 7604...
There is a new version of yours. Could be bug fixes for yours.

Do you know for sure if this fixes the ARP issues?
That's hard to tell, but worth a shot.
I would have to know a lot more about your topology and what else you have in the mix that could have proxy arp enabled and sucking the arp entries away from your 7604.
You could always increase the arp timeout. 4 hours is the default timeout period
It is an interface command to increase the timeout
arp timeout <seconds>
Default:
arp timeout 14400
else, i would open a TAC case to find out what is causing the issue to start with and why it takes 8 minutes for the network to start working again.
