Which OpenLDAP client lib version are you using?

Did you build python-ldap against OpenLDAP's libldap_r? This is strongly
recommended for multi-threaded client apps.

Which version of python-ldap are you using? There were some fixes in
python-ldap 2.0.4 for 64-bit platforms.

Could you please try to reproduce this problem without Zope? Maybe some
small multi-threaded client app sending similar LDAP requests to the server?

Ciao, Michael.
