It's possible for NaniteStaticMeshesInFlight to never be decremented because all the background workers are waiting indefinitely for the ones in flight to complete their static mesh build.
set landscape.nanite.maxsimultaneousMultithreadBuilds to a non-zero value.
launch some nanite landscape builds on very large landscapes
it will eventually hang.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-220638 in the post.
