      If we have multiple jobs which uses distributed cache with small size of files, the directory limit reaches before reaching the cache size and fails to create any directories in file cache (PUBLIC). The jobs start failing with the below exception.

      we need to have a mechanism where in we can create directory hierarchy and limit number of files per directory.
