Strange Cluster issue

[sahostking]

Setup new cluster and all works great. But every few minutes it looses connection and then I get no quorom error.

I then restart corosync on the server I added to the cluster which is empty and all works again fine for a few minutes.

I see this occurs in logs:

Actually looks like it varies. Sometimes I must restart on the one I created the cluster with and then other times on the empty new node I added to the cluster. But restarting corosync always seems to work for 5 to 10 minutes.
