Hi all,
I'm using Buchan's package of openldap2.4.22 x86_64 on RHEL5.3.

I'm able to reproduce a crash renaming an entry in my tree. I'm doing
this by using phpldapadmin. When I restart the engine I can see the entry
with the name changed.

I'm trying  to produce a core dump and subsequently file an ITS, but
I''m not able to have the core generated.

I changed /etc/security/limits for the ldap user and some other RHEL
specifics to not limit the size of the core.
If I look to  /proc/<slapd_pid>/limits I can see the following:

[root@ldap04 14527]# cat limits
Limit                     Soft
Limit           Hard Limit           Units    
Max cpu time              unlimited

Max msgqueue size         819200              
819200               bytes    
Max nice priority         0                   
Max realtime priority     0                   

After that I do the rename, the slapd crashes and the core dump isn't

Any idea?
