Here is a copy of the rc script that was distributed with flowscan (with
some modifications). It will now start (and stop) cfdcollect in addition to
cflowdmux and cflowd. This fixed my memory problem.

Steve ... I have not solved my memory problem. Your solution sounds very
encouraging. Could you email me a copy of your modified script. Thanks.
(Based on the number of people having this problem, you may want to post
it to the group as well.)
