For anyone using passive checks with nsca or any other xinet


This from my /var/log/messages:
“Deactivating service nsca due to excessive incoming connections”

Read this:

What I did is this:
cd /etc/xinetd.d/
vi nsca
Add this line to nsca
cps = 1000 30 Or whatever you feel is adequate.

This may help those that are having trouble with very large #'s of passive checks. I recall a few posts about unexplained troubles with hanging/etc.
