OK - now I get it ;-)
You can try to run the prog with moe niceness such as:

#nice -3 startcommandofyourprog

It allows jack to lock down memory. The RAM will only be used as needed
by jack. That is: if RAM is needed jack comes first to the amount given
in this line. If jack does not need all of the memory, other apps can
use it as usual. I have 1 Gig RAM and allow jack to lock up to 920000 -
works perfectly well.....
