OK, thanks for the explanation. > Most important is that vkernel didn't crash or hang :) > I assume that you didn't pass -n1 to the vkernel, right ? I used -n3 and -n16 but vkernel didn't crash or hang in either cases, so I tried it on the real kernel too, but so far all tests ran fine and I haven't managed to crash :). Oh, t_mq_send failed at line 56 after raising kern.mqueue.mq_prio_max to 200, but if I put it back to default (32), the test passes. Is it expected too? Cheers.
