All incoming connections are denied

All of a sudden this morning our 6 node cluster stopped taking connections.
6 of the nodes showed 0 connections, while nodes 4 and 5 showed 200 existing connections.
At the time, compaction was happening, and it stopped at 53%. I got this to stop by updating the bucket settings to only compact when at 50%, and between the hours of 10pm and 6am. Then the status went away.
I tried to remove one of the servers and rebalance the cluster, but that didn't seem to work. It's now been stuck at "rebalancing" for a couple of hours now. Even after issuing a "rebalance-stop" command.
After having one of our LInux guys look at the logs for CB and Linux found nothing, we decided to reboot the primary node. That went fine so far, it came back online and loaded the keys, and the access log and now it's in a pending state, most likely because it can't complete a rebalance of the cluster.

I ran cbcollect_info and have attached the zip file.
Let me know if you need further information.
Thanks!
