The fix is quite easy -- you can safely delete any zero-length files (while the node is down!).
How it got to that state is less clear. The "every three minutes" suggests that the vnode triggers a merge only to find there is nothing to actually merge. It is odd, however, that it doesn't clean up the big list of files. If you delete the zero-length files and bring the node back up, does it get back into this state again? D.
