I've just come across your problem report which you posted to the
"openldap-its" mailing list in this year's May:

  http://www.openldap.org/lists/openldap-technical/201605/threads.html#00079

Today, I encountered a similar hang of our OpenLDAP 2.4.30 server on a
Solaris 11.3(.11.6.0) host.

It is quite interesting that the function "bdb_tool_entry_close" doesn't
seem to play a role in my case, but "ldap_pvt_thread_cond_wait" and
"ldap_int_thread_pool_wrapper" do seem to.

My questions to your address and to the mailing list are: Has the
bug/problem been fully analyzed and has it been fixed in the meantime?
Mark, did you have another hang of this kind or any similar problems
with your OpenLDAP installation?

Thank you very much in advance for any helpful hints!

Kind regards,
Steffen
