Remote Replication Failure - Error getting list of available devices from agent

Version 6.16.1 introduced transfer statistics to Remote Replication tasks, which can increase the overall time needed to exchange disk safe statistics between Backup Managers in environments where higher priority tasks are running. Priority will be given to backups (replications) and restores. If this exchange takes too long to complete, it's possible for the Remote Replication task to time out before it can complete the exchange.  

 
The following errors may be seen in the task logs:  

Solution

It is recommended to increase the agent network timeout on both the Source and Target Backup Managers where this timeout is observed.
