We are running a cluster with 2 CUC server with version 8.6 on them, after a recent reboot of both server we were having replication issues and I was able to solve the problem following some steps from a different forum post about dbreplication resets.
we are currently still experience an issue when logging into the CUC publisher via the web interface we get the following error message "Communication is not functioning correctly between the servers in the Cisco Unity Connection cluster." and when logging into the subscriber we receive the same message along with "The Cisco Unity Connection cluster subscriber server has changed to Primary status(failover has occurred)."
Both the Publisher and Subscriber are currently running in a Primary state and when I got to use the Cluster management tool all the buttons are greyed out so I cannot change anything.
here is an out put from the Publisher:
admin:show cuc cluster status
Server Name Member ID Server State Internal State Reason
------------ --------- ------------ ----------------------- -------
001 0 Primary Pri Active Disconnected Normal
002 1 Disconnected Unknown Unknown
Database replication is not active
Output from the Subcriber:

Runtimestate looks good to me:
DB and Replication Services: ALL RUNNING
Cluster Replication State: Replication status command started at: 2015-09-28-07-06

Use 'file view activelog cm/trace/dbl/sdi/ReplicationStatus.2015_09_28_07_06_55.out' to see the details

so from what I can see replication is working and the devices appear to be talking to each other so why am I receiving these error messages and how can I fix this issue?
