I've seen this exact message when loading large sound fonts in Fluid Synth.
I had 256MB at the time.

Jack takes more memory than you first think, or at least it reports that
it's using a lot. If you have lots of free memory then this is not likely
the problem. I only offered it as an alternative idea, not as a solution.

It could be, I suppose, caused by where you are mounting the Jack tmp
directory. You might reply back with both:

1) the results of 'top' before you start Jack.

2) Your fstab file contents

Please remember Steve's comment. Possibly there is a permissions problem.
Could your shmfs only be allowing root to gain access?
