[Jack-Devel] jackd on low memory embedded systems

Hi there, I am wanting to run jackd on low resourced/power embedded systems (running Linux). When I run jackd on these systems it tries to lock down way to much memory ... much more then is available. Is the amount of memory locked down by jackd configurable ? Or is it an operating system set thing ? Does anyone have any constructive ideas or suggestions for running jackd on these low resource embedded systems ? thanks Matt
