Have a dsfw server that ndsd just up and died today. xadcntrl validate
showed nds dead, all but 3 dsfw services were unused.

Try rebooting the server does not help. It hangs booting up on waiting
for LDAP server to be ready, keeps showing LDAP server not responding.
Keeps showing a previous version of ndsd not shutdown properly &
ignoring the previous pid, and LDAP not listening on TCP or TLS port.

It eventually boots up but ndsd will not start.

Any suggestions on things to check/fix would be greatly appreciated.
