Knowledge Base article:

Summary

The replicating virtual machine has missed more than the configured percentage of replication cycles.

Causes

The network and storage subsystems are unable to handle the replica traffic.

Resolutions

Increase the network bandwidth between the primary and replica site or ensure that there is sufficient IOPS headroom in the primary and storage subsystem which can handle the replica traffic.
