I have a ASA 5520 with 512mb of memory. Over the last fiew months the memory has increased from 25% to and average of 65%.
I have added about 10 VPN's recently which increased in by 10%, but the other part I can only think it's from our WAN. Our WAN is connected to a VLAN on a Cisco 3750 that is trunked to the ASA's 0/2 port.
These VPN's and WAN offices are controlled using numerous ACE's.
Are there any methods to show what could be using the memory?
