[Nagios-users] NDOUtils 1.4 Stability

So ndomod will take the nagios process with it.  That does not sound
very comforting.  I run a 24x7 monitoring environment complete with NOC
team, and having our monitoring system just stop tends to annoy upper

Does this happen very often?  I'm not too worried about it if the system
is mostly stable.  What kind of uptimes have people had with this very
handy tool?

I don't think that is strictly true. Since ndomod is running in the  
same process space as Nagios, a problem with the broker module will  
cause the main nagios process to die too.

However, a failure at ndo2db (that writes to the db) will not affect
