I installed 2.9.20 (I compiled and installed the Debian 2.9.20-2
source package on an Ubuntu Breezy machine), and I'm still getting the
exiting with signal 11 (and sometimes signal 6) errors, though there's
no backtrace now. It's happened about 5 times since I upgraded to
2.9.20 a couple hours ago. The server is still responding ok to
queries, but all the errors don't make me real confident.

Thanks for any help you could offer.
