I hope someone (jhb?) is working on it We like to work on it. But so far I haven't seen someone provide the =20 necessary debugging (maybe jhb got something and I didn't got a CC). =20 We need a ktrace of it. Most of the time a wrapper script is called when running a linux =20 program. This is at least true for skype and acroread. So there are =20 two possibilities: - run "ktrace -i" and hope the mixed information (FreeBSD sh and =20 linux binary) can be decoded - modify the wrapper script to run ktrace on the real linux binary To process the ktrace.out file, you need to use the linux_kdump =20 program. I made a package (32bit) available at =20 http://www.leidinger/net/FreeBSD/ Most interesting is the information which syscall is called before the =20 coredump, but the entire log would be ok too (please don't send it to =20 the list if it is large). So if anyone is able to provide this =20 information: we prefer to get it even from several people instead of =20 not at all.
