dunno what to tell you.
I don't think the hardware in-and-of itself is the issue with snort not
(apparently) logging much/anything after 12 hours or so.
Obviously more ram is a Good Thing(tm) -- and ram is dirt cheap right
now, unless you need SIMM's -- but if the memory usage is holding steady...
And the number of rules you are running is reasonable.
There have been several threads over the last six months about snort
doing something like this, or snort dying completely, but I haven't
really followed them as it's not been an issue for me.
You may want to check out:
for the snort archives.
HTH a little..
