RE: (ITS#7401) OpenLDAP 2.4.32 - deadlock issues

[vb4607@att.com]

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

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?
