Thank you so much for the quick reply. We are a bit hesitant to try 4.7.25 as it is a 4 year old product. What about version 5.1 (5.1.29) as it is mentioned on your Web site (http://www.openldap.org/software/release/readme.html)?

Sincerely,

Venkatesh

We have been facing occasional deadlock issues when using OpenLDAP in multi-master mode (4 servers). It looks like deadlocks are occuring on objectClass index (eq). We have been using OpenLDAP 2.4.32 with hdb backend (BerkelyDB v5.3.21) on Red Hat Enterprise Linux Server release 5.5 (Tikanga). We tried to upload the DB stat reports on ftp.openldap.org/incoming/, but looks like the server is out of disk space. Some of the traces are provided below:

Your traces look much the same as ITS#7378. However, as noted in followup#4 to that report, there's no code path in back-bdb/hdb that can legitimately cause this situation. Can you switch to BDB 4.7.25 and still reproduce the problem?
