https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=293127 --- Comment #14 from Mark Johnston <markj@FreeBSD.org> --- (In reply to yuan.mei from comment #13) oh, interesting. Is the a stack trace? An nfsd thread faulted on 0xdeadc0de, which implies a use-after-free somewhere. If you're willing to try it, you could test a GENERIC-KASAN kernel, that should help catch the UAF as it happens. Note that such kernels are quite slow, and aren't very well-tested on hardware, so you might run into unrelated problems. -- You are receiving this mail because: You are the assignee for the bug.home | help
