Yup.  2.8.

It never happened with sophie 1.X, if I recall.  It's been happening with
sophie 3.X consistently through SAVI upgrades.

What would be helpful?  Core dump?  Thread status?  The truss is kinda
useless.  Let me know, I'll be happy to collect it when I can.  I agree,
it seems like there's a thread problem given that the process is clearly
"alive".  Perhaps a kill -HUP might reset it without killing it?
