Well I have tracked down what appears to be the root cause.  The above
made me run a loop of ldapsearch queries against our ldap farm and I
found that periodically I would get a return missing the exact paths
we're seeing being removed then re-added over and over.  We have a CSS
setup to handle load balancing and failover for the ldap farm and I
found that one server behind it is giving out the broken maps.  Working
on getting that fixed ASAP (I'm not the ldap guy).

No details on why this happening over several hours would eventually get
the daemon into a state where it finally core-dumped though.  But fixing
the map results should make that not happen anymore anyway.  If I can
manage to catch a debug output and/or strace of one that still
core-dumps before the ldap side is fixed, I'll pass it along.
