Did anyone get this resolved?

We replaced our external router and now the messages log is full of:

Oct 8 06:14:09 dc nslcd[2381]: [6e31f4] <passwd="ldap.ldap"> no available LDAP server found, sleeping 1 seconds
Oct 8 06:14:10 dc nslcd[2381]: [6e31f4] <passwd="ldap.ldap"> failed to bind to LDAP server ldap://127.0.0.1/: Can't contact LDAP server: Transport endpoint is not connected
Oct 8 06:14:10 dc nslcd[2381]: [6e31f4] <passwd="ldap.ldap"> no available LDAP server found: Can't contact LDAP server: Transport endpoint is not connected

Any thoughts?

Thanks
