ERROR: local exporter [default_local] - failed to delete indices

Since few node restarts, we are getting the error message
local exporter [default_local] - failed to delete indices
I am not sure what exactly is wrong, but it relates to Marvel. The cluster is GREEN and working as expected, but the log keeps getting populated with this error. Doing some reasearch I realize that the error is related to the marvel indices.
Using Marvel Version 2.3
Could there be anything wrong with cluster which I am not able to see?
