hmm, in 3 you said there is no VIOS, now i am confused. Please describe your (physical and virtual) network setup in detail, from the switch to the kernel.

I don't think this is default. I even suppose this is why you lose connectivity sometimes. If a packet comes in on interface 1 this doesn't necessarily have to answer if two (or more) interfaces are in the same subnet. It could be any other interface in this network too. If your en1 answers and this traffic is routed to the loopback device, the connection would never come to pass.
I suggest you investigate this, IMHO this is the most likely source of the problem.
For a proper routing table you need 3 entries:
1) a default route, telling the system where to send everything for which no rule exists,
2) route directing everything on the "home net" to the interface in the net,
3) a loopback, directing 127/8 to lo0.
For instance: your network on en0 is 10.10.10/24, your IP is 11. Your second network is "10.10.20/24", IP is 11 again. You will need 4 rules for that:
1) default -> nearest router, say, 10.10.10.1
2) 10.10.10/24 -> 10.10.10.11
3) 10.10.20/24 -> 10.10.20.11
4) 127/8 -> 127.0.0.1
I hope this helps.
