can you do an update, via:

apt-get update
apt-get dist-upgrade

it seems that you use an older package versions than available in the repos.
We use UNIX sockets for securely forwarding the migration to the other 
node, your log shows that it uses TCP ones..

And ensure that both nodes are on the same versions, else you may get 
problems when migrating from new to old..
Old to new works.

cheers
