yes, Keep your eye on that and watch it. .tons of free memory right now..
Not sure if this is a gradual degradation or if, all of a sudden, something is slamming the nbx and using up memory.
A better way of watching memory is to go to http://ip_address/sec_cont/ops/memory.htm
In the memShow/Snapshot period, put in 30 minutes, then click on "take snapshot now".
this will take a snapshot of your memory every 30 minutes and write it to the memory.txt file.
Then you could see if this is a gradual degradation or if all of sudden memory is being used up.
