Sorry, that has not been my experience. There is no memory leak in CF that
I have found, just as there is no memory leak in ASP. However, in CF and
ASP code can be written that does not release memory. In ASP, this is easy,
in CF it's a little harder. I have ran an NT - CF Server getting over 1
million hits a day for over 6 months without a reboot (nstorm.com). The
only reason I had to reboot was my company got bought and we switched
buildings. If your code is solid, there is no memory leak in CF 4.01 I know
for sure. Currently all the sites I'm in charge of use cf 4.51 and they do
not show signs of memory leaks. I'd suggest having the code looked at by a
Senior developer in CF. They will be able to find the problem for you.
TIPS: Don't store large amounts of information in application or session
variable
Check for endless loops.
Don't run large scheduled tasks on your production box.
Lower session time.

Yes you are correct. There is a memory leak with Cold Fusion. We currently
run our server with 4GB of ram on each and have not had "many" problems. I
have spoken with a couple of people at Albany CF Users group and found that
they do not suggest running a production CF Server with less than 512MB of
ram. Event then I would keep an eye on the memory usage. As it was explained
to me the server is grabbing memory to use when it access your queries. Then
the server holds on to this memory in the event you may need it again. Some
helpful things I have been told are;
1) Make sure your databases are not on the CF server.
2) Scheduled reboots.
3) Structures such as cfloops eat up memory fast.
4) Make sure no session variables are just hanging out on the server.
These few thing have made the memory leak less of an issue, but it still
becomes a problem every once and a while.
Hope this helps you out.
