The Hyper-V-VMMS Log Contains Event ID 29414

In our Hyper V 2012 (non R2 !) environment, the hosts are reporting errors like the below....

'9E0348EA-1374-481B-A3C1-1F2672DE1DD3' failed to create scheduled task based on information stored in the respository: Unspecified error (0x80004005). (Virtual machine ID 9E0348EA-1374-481B-A3C1-1F2672DE1DD3)

------ There is no real VM with this UUID.. Maybe a deleted one..

Question I have is :

Should I worry about the above?

If not, how can I stop the error being created in Hyper -v vmms log?
