tinc - Mar 2016 - Multiple Tinc Vpns Crash

I use 3 Ubuntu server 14.04 as KVM guest.

Now I run 5 tinc vpns in switch mode.
I use the same key for every vpn.
Every kvm has connect to the two other servers.
I need 5 vpns to have 5 networks connected but seperated.

1 vpn was running fine, but now that I run 5 vpns, my kvm crashes sometimes.
Especially when I stop tinc.
I used tinc 1.0.26 from repo.
Now I tried tinc 1.1 pre, same problem but less often.

Any help or idea why system crashes?

So the KVM instance itself crashes? Or Linux inside the VM? Any error
messages you can salvage?

How much memory do the KVM instances get?

Only guest system crashes. But I have to make hard reboot.

1 gb ram, 3 cpus. System does make lots of traffic, but not via tinc.
