Just noticed that my ASA5505 SEC+ memory usage when idle without any activity is constantly about 120MB. ASA version 8.0.(4), ASDM 6.1. I have another ASA5505 UL box which is with ASA version 7.2(3) and ASDM 5.2(3) but it uses only 38MB of memory. So my question is what is the typical memory usage, what can affect it significantly and finally why there is so big difference between those two devices.
