ssh: connect to host 192.168.XXX.XX port PPPPP: No route to host
The failing servers are on fremont793 and fremont736
There is nothing significantly different between these 2 systems and the other 14, however I have never seen a connection count difference from the expected 720/day of more than 1 on any of the others.
I added some additional logging to see when the errors happen (although since I am now talking on the primary IP may not see any) and while this particular activity is not critical, we do have other inter-system communications using the private IP that are.
Any suggestions or guesses about this would be appreciated.
