That particular machine has its /usr/ports, /usr/ports/distfiles, and /usr/ports/packages mounted via NFS from another FreeBSD machine. The machine that crases also nullmounts those filesystems into each jail. I'm not completly sure that this is the reason the machine crashes, but i suspect that is the reason. What can I do to figure it how? What kind of debugging knobs do I need to apply to learn more about the problem? -- chs,
