Let's all thank Rick for sharing his story. *clap clap clap*

Without using even marginally over-spec'ed servers I have yet to run out 
of memory, and I tend to store things in session, including shopping 
carts, whenever it's necessary or convenient to do so.

Maybe it's just because I don't store huge objects in session (in 
general), but even on a Torque-based app when I keep Torque beans in 
session I'm still not running out of room. (That's a relatively low-load 
app, though; it's never been stressed.)

On an internal app at one of my clients, not using torque but more or 
less plain old beans with specific functionality on a 1G machine with 
(typically) 500 users connected at any given time I was never in danger 
of breaking anything, though. (DB hosted on another machine.) Even if 
I'm storing, say, 100K of crap in the session for each user (which I 
definitely wasn't), that's 50M of session crap. That's a lot of crap. 
But it's still like 5% of my memory. (Right? I have a fever today and 
math cells are the first to go--marked for early swap.) So it's 
difficult for me to get all worked up about it, especially considering 
time and maintainence constraints.
