Error description
When afmFastCreate is configured and a normal file gets copied - it sets the cache/primary mtime at the home/Secondary during file create time itself. Later if Write gets interrupted mid-way and later a Resync is run on this fileset - the same file is not copied over fully stating that the file is already in sync. It involves a small race to get here.
