VCSA Replication to DR Host is Failing

[rmai]

I having ongoing issues with a Veeam Replication job to a DR host that includes a single VMware VCSA VM that constantly fails. The VCSA VM has 13 disks. Every other Veeam Replication job goes through just fine. The failing VCSA Replication job output below is from the Action pane in Veeam Backup and Replication 9.5u4.

Case No.

Which logs should I be looking in for more for more information?

This was solved by:
1. Disabling automatic selection on the source and target proxies in the failing Replication job.
2. Lowering the max concurrent tasks on the source proxy.
