Constantly getting "Reopen for Clustered Client Failover registered application has failed for FileObject " error in CCFilter eventlog.

Hi everybody.

Hope somebody will be able to help me with the following issue.

I have the following environment configuration:

1. WFC cluster (cluster1) contains 3 nodes - sql1,sql2,sql3

2. sql1 and sql2 can run single shared instance SQL server

3. Node sql3 is a standalone SQL server.

4. AlwaysON is turned on shared instance and standalone SQL servers and availability group have been configured for multiple DBs. So sql3 is a replica of shared instance.

I'm  constantly getting following error in Microsoft-Windows-CCFFilter/Operational logfile when I execute SQL DB/Transaction log backup maintenance plan on my shared instance SQL server (sql1 or sql2):

Log Name:      Microsoft-Windows-CCFFilter/Operational

Description:
Reopen for Clustered Client Failover registered application has failed for FileObject 0xfffffa801cbb08a0 to \SQL3\Backups\Logs\DB1\DB1_backup_2014_10_24_060003_3960528.trn with status 0xC0000034

Getting multiple mentioned errors for every single DB I'm running my backup maintenance plan against. The maintenance plan gets executed on SQL1 which is shared instance machine.

Any ideas of what can cause this and how to fix it.

Thanks in advance.
