Off the top of my head, piranha hanging (or even crashing!) shouldn't
affect the load balancing traffic.  Piranha controls the routing
assignments, but it doesn't do any routing itself - the routing is done
in-kernel in the IPVS modules.

So, I suspect that lb1 (or rather, its kernel) might be hung as opposed
to piranha...

Can you get a serial console attached to lb1 and see if it's
panicking/hung?
