It doesn't look like a dlm problem, but a network problem. ;)
So your first error is o2net_connect_expired.
So it seems that the 3rd node can't connect with node 2.
Could you please check the error message in node 2?

btw, I would deem that the cluster.conf is the same among the 3 nodes, 
and you you can connect to 7777(which is used by ocfs2) of node 2 from 
node 3.
