I just upgraded our Director to 2.2.29.1 from 2.2.26, and now my dmesg and /var/log/messages are getting flooded by these errors:

Any ideas?

Try get a core dump and run it thru gdb.

Also, dovecot should log some kind of trace and message into syslog or whatever log_path points to.
Only this:
May 02 09:00:34 lmtp(17467): Fatal: master: service(lmtp): child 17467 killed with signal 11 (core dumps disabled)
.. and lots of them.
Then try enable core dumps, and see what the core says.
sysctl kernel.core_pattern=/some/writable/dir sysctl fs.suid_dumpable=2
and if you are using systemd, you also need to add
/etc/systemd/system/dovecot.service.d/coredump.conf
with
[Service] LimitCORE=infinity
