First of all, I don't know how active this list exactly is etc, as I just
subscribed. So I'm still a bit glowing green ;).
Since about 2 weeks I'm using Nagios to monitor about 50 servers for the
company I currently work for. But I've got a problem with just one tiny
thing I can't seem to be able to fix.
Most of the ping tests work great, however there are some that start
flapping for no reason. Sometimes it works, sometimes I get back an error.

I keep getting the 'Could not open pipe' errors at random intervals.
Does anyone perhaps know why this happens ?
The firewall configured for this, will allow all traffic from and to the
server that's using nagios.
With kind regards,
