I think these log lines from messages are the problem:
Oct 11 14:46:35 lhi1 nsd: [11/Oct/2002:14:46:35][1661.1024][-main-] Notice: nsd.tcl: starting to read config file...
Oct 11 14:46:35 lhi1 nsd: [11/Oct/2002:14:46:35][1661.1024][-main-] Warning: nsd.tcl: nscp not loaded because user/password is not set.
Oct 11 14:46:35 lhi1 nsd: [11/Oct/2002:14:46:35][1661.1024][-main-] Warning: nsd.tcl: nsssl not loaded because key/cert files do not exist.
Oct 11 14:46:35 lhi1 aolserver: nsd startup succeeded
Why? As I mentioned, it has been working for a long time with no configuration changes.
