I have been core dumping my panics to a remote machine and been using gdb to figure out where in my NKE it keeps crashing, and it appears to be randomly crashing at different parts. maybe due to the fact I call _MALLOC and get space but it never allocated it. because I have a structure pointer that I allocate and store things in there, but it is crashing at this line: one->thedata = data; To me one must not be allocated so it crashes, how do I ensure that calling _MALLOC is going to give me space and not crash my NKE??? Are you using M_WAITOK? M_NOWAIT is good if you don't want to block. You'll retry somehow on your own, or abandon the attempt, or ... M_WAITOK means that you want to wait until the request can be fulfilled. That may take a while. This email sent to site_archiver@lists.apple.com
