might be interesting to add an 'strace -fF -o zope.trace ...' to
the relevant section of the startup script (the zope script)
so that we might get an idea what happens and why it fails

do they stay 'forever' then, or do they fail/die after some time
too, when started _after_ the init procedure?

are you sure that the 'only' thing you changed was the kernel and
util-vserver? maybe a distro update too? maybe a new hardware?

that's not too unusual, and you might fix that in the shutdown
script by killing off all kind of stuff inside the guest, which
just seems not to be done atm ...
