mdcache is different from "FD" cache. I don't think we found an issue with
mdcache itself. We found couple of issues with "FD cache"
1) https://review.gerrithub.io/#/c/391266/
2) https://review.gerrithub.io/#/c/390496/
Neither of them are in V2.5-stable at this point. We will have to backport
these and others soon.
