guimfacq,

You could try increasing the memory and message limits set for STREAMS
using the -c and -C flags to the 'streams' utility function.  They are
likely set to default values that might inappropriately low for such a
high performance, large memory system.

Nevertheless, the assertion failure might be related to something else,
(most likely an SMP race condition aggravated by waiting for a buffer).
I think that you will need to contact Intel to resolve the problem.
