Description
Per solid uri semantics, two resources that have uris differing only in trailing slash are mutually exclusive.
When two simultanious put requests came for resources a/b (say, with content type text/html), and a/b/, and neither of them exists before, It can lead to creating both resources, (and may lead to creating a/b$.html, a/b/ in filestore).
Issue also can happen, on put requests like for a/b, a/b/c/d.txt, as solid requires creating intermediate containers.
