I installed a server (RHEL5 x86_64) with three instances of OpenLDAP 2.3.43.

ldap      6572     1  0 May24 ?        00:49:12 /usr/sbin/slapd -u ldap -g ldap -h ldap://X.Y.Z.104:389 -f /etc/openldap/slapd.conf -l LOCAL4
ldap      6612     1  0 May24 ?        00:49:09 /usr/sbin/slapd -u ldap -g ldap -h ldap://X.Y.Z.105:389 -f /etc/openldap/slapd_i3.conf -l LOCAL6
ldap      8031     1  0 01:01 ?        00:01:26 /usr/sbin/slapd -u ldap -g ldap -h ldap://X.Y.Z.104:389 -f /etc/openldap/slapd_i2.conf -l LOCAL5

At first everything worked perfect but after several days working properly one instance stopped.
I started the instance again but after several days one instance stopped (not the same).
I don't understand what happens. Any help is very useful to me.

Thank you very much.
