We are getting intermittent problems with NCP volumes becoming unavailable due to ndsd stopping. If I restart ndsd the volumes become available again.

I see in another thread someone recommends
"Check in your /etc/nam.conf for preffered-server is the right one with a replica, and add "alternative-ldap-server-list=<ipadress" row for adding other LDAP servers as well..."

When I check my nam.conf file the preferred-server ip address is that of the server itself. Is this correct or should it be the address of a server in the replica ring?
