This appears to be a Cyrus/SASL issue.

In particular, your trace of thread 1 shows that slapd is shutting down the SASL library and SASL is trying to tear down libldap. Inside slapd, the Cyrus SASL library should never be touching libldap. As such, you should check your SASL configuration, you probably have a plugin enabled that shouldn't be.

You're right. Removing cyrus-sasl-ldap-auxprop solved this problem. Sorry for the noise.

Ciao, Michael.
