Failover cluster issues 1650, 5120

Hi,

We have strange issue with our communication between failover cluster nodes. Many errors are 5120 

” Cluster Shared Volume '3par-alpha-ssd-01-dedup' ('3par-alpha-ssd-01-dedup') has entered a paused state because of 'STATUS_CONNECTION_DISCONNECTED(c000020c)'. All I/O will temporarily be queued until a path to the volume is reestablished.”

If we change to Informational so we can see many 1650 errors like ” Microsoft Failover Cluster Virtual Adapter (NetFT) has missed more than 40 percent of consecutive heartbeats.

Does anyone else had the same issue with communication and failover cluster hosts with these errors.
