I wonder if anyone else is having this issue?
I have a VPN connection (OpenVPN) between two servers in two locations.
Every 10 min, from the 'server' end I run:
where x is a list of hostnames
Out of the 24x6=144 times I ping this server, I'll get about 3 fails a day.
Immediately after receiving a fail warning, I ping the server and it's up.
