You need to provide MUCH more information about the crash. The complete trap information, info about which routine the trap occurred in (via the kernel namelist) or (better) a symbolic traceback if this is available. Just saying that you had a "trap 12" is not useful other than to say that you're having a problem of some kind. -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
