Yes, running datastore inconsistency check confirms the issue is related to it. My personal suggestion is to use oak run for any of these type of activities like consistency check as it these operations are memory heavy.
I have run the data store consistency check from root node: "/"
I got similar kind of error there as well .
2) should I run data store consistency check in the prod enviorment because these kind of issue is instance or enviorment specific so to get the correct corrupted file I have to work on live server prod from where I got the logs .
