Ghosts in the machine? :)
Beyond ensuring that the machines' network settings are good, that
they're not accumulating errors at the hardware level (check ifconfig
output), and that they're not interrupting themselves off the planet
(/proc/interrupts is a good place to start), I have no idea.
It still sounds to me like the fault lies below the application layer.
Speaking of interrupts; you say you have eth0/1 bonded. Please make sure
that you haven't got several hundred megs worth of traffic looping
around your ethernet because of that. If you have you could be dropping
packets simply because your kernels cannot keep up with the traffic load
- a layer 2 loop somewhere could cause an effective DoS condition like
this quite trivially.
What mode is your bond interface in?
I've never used heartbeat, so I can't really suggest anything else.
Anyone else got any clever ideas?
