Couldn't say, but I would think not. Nagios should be running as an
unprivileged user so it really shouldn't be crashing FreeBSD.
However I'm fairly certain I can crash my SMP FreeBSD 5.4 server with
enough ping activity over time, which indicates a bug somewhere in the
network stack (maybe a race condition, given that it requires a SMP
kernel). Nagios with a lot of hosts sends a lot of pings, which would
imply that Nagios could eventually crash the server as well.
However you said that Nagios process itself died - that would indicate
some other problem w/Nagios.
ps. now testing FreeBSD 4.11 SMP with 130+ simultaneous ping/arp -d's
(50,000 context switches a second!) and it has been rock solid for 30
minutes. 5.4 would crash within 60 seconds.
