High Memory Usage?

High Memory Usage?

I am running NFA 5.0.0 build 5002 on a server (running Linux) that has 2GB of RAM and NFA is using it all. The server when not running NFA is utilizing 25% of memory and after I start NFA it creeps up until it's using 100% (takes about 2 hours to reach 100%). System requirements say 1GB of RAM is enough, do I have a memory leak? Is this normal? Anyone else have this sort of utilization? I am monitoring 33 interfaces.
