+1 if you can't find any software issue,

but don't run memtest, disassemble and mount the RAMs again. If you've
got several RAMs, remove just one after the other. It could be that for
non-audio work most of your RAM isn't needed, but audio streams might
need much more RAM.

Do you get any additional output, when you launch ardour2 and jackd in a
terminal emulation?

A core dump might be useful too, if you get a segfault.
