SLAPD won't start



This is a resend as the original did not go out for some reason.

 

We have a 3-way multimaster configuration running on CentOS 5.11, OpenLDAP 2.4.40.  All three have been up for years, until the other day:

 

Slapd is running on two of the three (server names:  ldapserver1, ldapserver2, and ldapserver3).  Slapd stopped and won’t restart on ldapserver2.

 

From Logs on ldapserver2:

I have run db_recover on the dbase(s) on ldapserver2 but to no avail. 

 

Does anyone have any suggestions? 

 

Thank you in advance for any assistance.
