Hi,
i've tried to install the 1.2.9.8 testing version in our production
environment but there is a regular freeze/deadlock after a particular
search.
It is a search sent by outlook 2003 (you type the name of the person
and then click "Check the name" button that generates an LDAP
request). The person does not exist in the given subtree, here is the
corresponding connection in the logs :
[01/Sep/2011:13:42:34 +0200] conn=938 fd=129 slot=129 connection from

[01/Sep/2011:13:42:34 +0200] conn=938 op=1 SORT cn (1)
<end of access log, nothing in error log, server freezes>
The problem is reproducible each time, here is the interesting part of
the gdb trace :

I'll try to install the debug symbols and reproduce the stack trace
with symbol table after i roll back to our previous production version
(1.2.8.3)
