Is there a better way to call an external program under unix? I wasn't
aware of this... (I haven't noticed any big problems, the few times
where I have cfexecuted an external program)

| However, I would strongly advise that you stay away from
| cfexcute on unix systems if you can. Because of the way the
| fork() method was implemented on unix systems (which is what
| cfexecute calls under the hood to run the external process)
| it duplicates the amount of memory of the calling process to
| run the external process, which is crazy.
| So, for example, if your JRun process is currently taking up
| 1 GB of RAM (a pretty common JVM size), then cfexecute will
| run the external process using 1 GB of RAM, which will very
| quickly throw an Out of Memory exception. I learned this the
| hard way so I figured I'd save you the hassle down the road.
| In single-user testing you might not see the error because
| you might have enough swap space to create this second
| process, but any more than a couple of users will bring your
| system to a grinding halt. So I'm not sure what you're trying
| to do, but I would find another way to do it. Mind you, this
| is not Macromedia's problem -- it's a UNIX problem that is
| just a known implementation issue.
