It's killing the process that nsvhr is loaded in -- the master server.

nsunix. *shudder* That's probably 50% of your woes right there, all
in one lump.

Wow, lucky you. ;-)

I know with nssock, the nsvhr master nsd process really can't kill
the nssock slaves, but perhaps nsunix is a bit more fragile ...

If I were to place a bet, this is where I'd put my money. Perhaps
foolishly, but ...

When did nsunix start working? Wasn't it known to be broken somewhere
between 3.0 and now? Sorry, I haven't kept up on nsunix to know if it
has been fixed, and my poor memory can't recall any mention of any
fixes in the ChangeLog ...

NO traffic at all, or just very, very light traffic?
I think there's some web search engine's spider out there that feeds
nsvhr a HTTP request that it doesn't like, and it makes my nsd process
fall down.
If your process is dying with ABSOLUTELY no traffic, then I'd go
looking elsewhere. It only takes a _single_ HTTP request to cause
my nsd to die, so even at the dead of night, my monitoring tools
pick up that my nsd died and goes and restarts it ...
