I am in the final phase of a vpn deployment and am running into an issue with my PIX. It appears to have proformance issue once I reached the 90 + count for VPN connections into the device, Is there and if so what is the maximum number of VPN connect...

I am seeing the routing table converge on internal (90) routes on the ISL uplink to the switch. This is only changing the uptime on a few routes and not the entire table. (show ip route eigrp)
