We are experiencing frequent hangs in slapd. Once hung we usualy cannot continue to connect until we kill -9 the slapd process and restart it. The directory is used for 2 applications as user eDir and we are using it in production over 1 month - we have noted the busier the directory becomes the more often it hangs (now twice per week).

We have installed identical configurations on 3 environments, each has only one single server (no replication). There are 30k entries in the directory (production).

We are running:

RHEL 5.7 x64 (VMWare with NFS mountpoints) OpenLDAP 2.4.32 Berkeley DB 4.8.30 (4.7.25)

We were starting with DB 4.8.30, after downgrade to version 4.7.25 (according to ITS#7378 - https://www.openldap.org/its/index.cgi/Incoming?id=7378;selectid=7378) we are facing the same issue.

Note that BDB 4.7.25 is known to self-deadlock if you haven't applied all of the patches.
