Check_ping on debian

Hello,

I'm having a lot of false positives consistently with check_ping
Debian.  I've tried changing the default max packets and I'm getting
unexpected %s of packet loss.  If I do 5 packets sometimes I get 16%
packet loss, if I do 1 packet sometimes I get 50% packet loss.  Am I
misunderstanding something about how this works?  Those don't see like
percentages I should be able to get out of those packet numbers.

I have IPv6 disabled in Debian and I'm passing the -4 parameter as well.

I've been unable to duplicate the failures using the normal ping
command, but I can duplicate them using check_ping in a bash script.

Thanks,
