I'm just using it "out of the box" from the CentOS 7 bind-sdb RPM.

It was running okay, but the system hadn't been updated in a while
(again, internal system), and after it was updated this week, named
started crashing.  I don't know if it's a problem on the BIND side or
the MariaDB side - both were updated:

bind-sdb: 9.9.4-14.el7_0.1 -> 9.9.4-29.el7_2.3
mariadb-libs: 5.5.40-2.el7_0 -> 5.5.50-1.el7_2

Given the changes in bind-sdb are fairly minor (CVE patches), while
mariadb-libs rebased to a new release (granted, minor version change),
I'm more inclined to think that's where the problem lies, although it
could just be a combination of the two.

Now that I think about it though - the VM running this was also updated
from 1 CPU core to 2, so named-sdb probably went from one thread to
two... maybe you're right.  I'll check that out.
