We have found that some sites, when restarted with "svc -t", go into
a funky half-shut-down state and stay there. I don't know why, and
it seems to be very consistently some sites (all using PG) and not

Thanks! I do use "svc -t" when restarting, so I will try -k and observe
what happens. I'll also now look more carefully at the logs -- I think
there are some clues I haven't yet picked up.

reason to use -t, since i

I've taken a break to play with some PG logging on my development machine
