Environment

VMware Cloud Director Availability 4.x
VMware vCloud Availability 3.5.x
VMware vCloud Availability 3.0.x

Cause

This issue occurs when the threads used by the scheduler become saturated while it waits for responses from the offline or inaccessible Replicators, which prevents it from updating items in the expected timeframe.

Resolution

To resolve this issue, if a remote site is not currently needed for active protections or migrations then it should either be left running to maintain the cross site connectivity or unpaired before being powered down.

For more information, see the Upair Paired Sites section of the Cloud Director Availability documentation.

If a site is needed for active protections or migrations, then all Replicators in that site should be online and accessible.

Additional Information

This error can also be generated when the Cloud Director Availability appliances and virtual infrastructure do not have their time synchronized or there is a delay interacting with and processing API calls to the destination vSphere environment.

For more information, see Assuming task failed, because it's status did not update in a timely fashion" error when configuring replications in vCloud Availability
