When I run cvsup, the kernel crashes with a trap 12. Now I see from the various mailing list archives that a number of people have reported similar problems, but I have not seen any mention of a fix. One problem that I have of course, is that I am not getting updated source files, as it is cvsup that is crashing. I would surmise that there is a malloc probem in cvsup, when trussing the process I get a lot of "truss in free(): warning: page is already free." but I would not expect this to crash the kernel. I can reproduce the problem on a generic kernel. But my questions are these: Are there any identifiable kernel fixes for this type of problem that I can apply? Or do I have to upgrade to 3.2? I should explain that it is only cvsup so far that tickles this bug, but this is only 1 of a number of machines I am building, and although the others are stable so far, so was this one before I started running cvsup, so upgrading with so much work in progress is not quite a painless option. There was one suggestion in the mailing list to sidegrade to 2.2.8. Unfortunately this is an unsatisfactory solution in this case, as I need some features of the 3,x system on the other machines. I can supply stack pointer and crash information if required, but it seems that the problem has been seen on a number of occasions, although not particularly with cvsup as far as I can tell. Any information appreciated. Thanks Kevin Quinlan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
