JM, How are you doing today? Right before the file does not exist should be another path. Can you let me know if in that path there are a pointers from a split to 2ebfef593a3d715b59b85670909182c9? The directory may already exist. I have seen this a couple times now and am trying to ferret out a root cause to open a JIRA with. I suspect we have a split code bug in .92+
