SOLUTION:

This mostly happens when LDAP files are corrupted under the ../domain-name/server/AdminServer/data/ldap/ directory. A possible cause of corruption is when space on server is full. When the associated volume is full (100%) weblogic server will corrupt these files. Remove the replicas.prop corrupted file.

Rm -rf $Domain_name/servers/$server_name/data/ldap/conf/replicas.prop

And restart the server.
