This issue occurs if Site Recovery Manager reaches the limit of tasks it can run in parallel. By default, the maximum number of tasks is 10.
Workaround
To work around this issue when you do not want to upgrade, increase the maximum task limit on the recovery site from the default of 10 to 20.
To increase the limit:
- Open vmware-dr.xml (located in C:\Program Files\VMware\VMware vCenter Site Recovery Manager\config\vmware-dr.xml) in a text editor.
- Locate the section:
<vmacore>
<threadPool>
<initializeCOM>mta</initializeCOM>
</threadPool>
</vmacore>
- Add this line after <initializeCOM>mta</initializeCOM> :
<TaskMax>20</TaskMax>
Note: This line increases the limit to 20.
Example:
<vmacore>
<threadPool>
<initializeCOM>mta</initializeCOM>
<TaskMax>20</TaskMax>
</threadPool>
</vmacore>
- Restart the VMware Site Recovery Manager service.
