I just realized I replied off-list. I gave you a bunch of specifics, but I can't seem to figure out what's causing it. If I'm repeating myself here, it's only for others' benefit. It's an opennebula cluster with a handful of hosts. For some reason two hosts with newer kernels (3.10.34) it tends to happen more often. I'm considering isolating one kvm guest on one of the hosts, and re-enabling netflow. My collector sits across a vpn tunnel. The only other errors I see in the logs are related to polkit.
I'll run the single-guest vm experiment tonight and see if I can correlate any events with the netflow module flaking out.
