Actually, could this be worth trying (adding Ingo in CC):

Effectively in this specific test case I had 5 stuck process using each
100% of a CPU... although 3 other cores where still available so there
is (I believe) no reason why it should had starved that much.
Anyhow, that did not happend on all the other testing I made during the
past 3 weeks (except this one).
I restarted the this test (again using a 2.4.35.1 kernel), mde sure no
process where stuck :), and grabbed the ps aux + ipcs -q info (attached)
Again, the ipcs -q shows that the queue is getting full comparing to
SYSTEM 1 which always has a queue of 0.
Note: Also attached a top.txt file showing that the dispatcher uses 100%
of a CPU on SYSTEM 2. This never occurs on SYSTEM 1.
