Is there anything else in slapd logs?
I haven't been able to identify anything of consequence.
For example I found this with google: http://www.openldap.org/lists/openldap-software/200507/ msg00063.html
Aye, I saw that as well. Unfortunately, Howard points out that the author of that message was mistaken and, as near as I can tell, the only "solution" anyone could come up with was to upgrade. I'm already running the current stable OpenLDAP. I'll try to track down more info. -Ben
