You need to have the DEBUG option enabled in the ports or use the binary packages and set sysctl kern.sugid_coredump=1 first to also get coredumps for suid binaries like VirtualBox is. Once you have a core file please run "gdb /usr/local/lib/virtualbox/VirtualBox your_corefile.core" and send me the output of "bt full". -- Bernhard Fröhlich http://www.bluelife.at/ > On 4/26/11, Bernhard Froehlich <decke@bluelife.at> wrote: >> On Mon, 25 Apr 2011 20:00:54 +0200, Oliver Pinter wrote: >>> Hi all! >>> >>> I run in to reproducible vbox crash.
