Replication fails with "Specified argument was out of the range of valid values" (4041417)

After an upgrade or a clean install of Rapid Recovery 6 replication fails with the following error:

Exception chain:

• Specified argument was out of the range of valid values. Parameter name: One or more of the read buffers are not large enough for the number of records being read
• One or more errors occurred.

This issue is caused by a large amount of data trying to replicate.

1. To resolve the issue change the Volume Image Session Timeout on both cores to 60 minutes.
2. This setting is located under Replication tab -> Settings (icon that looks like a gear).
3. Restart the core services after making the changes.
