I got alarms from my pix515E tonight that the memory usage was at 82%..
This is pretty strange since we have extremly small traffic during the night.
My interface graphs shows almost zero traffic during this incident. So it doesnt look like an attack.
My mem is currently at 72% which I would consider high?
Pix515E# sh memory
Free memory: 18529040 bytes (28%)
Used memory: 48579824 bytes (72%)
Total memory: 67108864 bytes (100%)
Pix515E# sh conn count
1332 in use, 12988 most used
Pix515E# sh xlate count
955 in use, 2030 most used
Running the 7.2(2) IOS on it..
Should I consider 72% memory usage normal? The load isnt even close on what the Pix should manage without any problems..
Is there some command that I can run that will free up some memory ? (If the pix internal garbage collector isnt doing its job?)
