The Linux binaries run on FreeBSD in compatability mode. When server.exe is run on a system emulating a 2.4.2 kernel it reports:
FATAL: kernel too old
and then causes a segmentation fault.
I understand that a 2.6.x kernel is required but the segmentation fault seems like a bug.
Thanks. I don't have access to a FreeBSD box, so I have no chance to debug this. I will leave the bug open; maybe someone else here can do something about it.
