I wish I could avoid this misunderstanding ! The fact is that I was expecting some hints to track down the problem on myown, especially concerning the FreeBSD behaviour in case of free list shortage. Also, I would appreciate to know if my understanding of the figures I got from 'cnt' or of the scheduling behaviour with regard to kernel preemption is correct. I think this would be helpful for me to build the code sample you are requesting. > I do appreciate your mini-kernel debug howto, I've got it saved > for future reference. I am sincerely happy that I could provide something helpful ... Well, actually, it sounds that I did go to far to be able to retract myself, so I will let you know of any progress I will make asap ;-) Cheers, Xavier To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
