The gateway IP is a layer-3 switch, and I think sometimes it just is not responding to ICMP echo request in a timely fashion (traffic is routing just fine though). How is the HA ping implemented? How many requests does it send (and how many responses are required to be considered "good")?
I see ovirt_hosted_engine_he/broker/submonitors/ping.py that only one packet is sent. That's probably not a great way to do things; there are a number of routers/firewalls/etc. that put ICMP echo requests to the device (as opposed to through the device) at the very lowest priority, and drop them under any load. A better way would be to send multiple requests, with only one answer required. "ping -c 1 -i 0.2 -w <timeout> -W <timeout> <IP>" should do that. -- Chris Adams <cma@cmadams.net>
