bindfs, osfuse, sshfs & macOS Sierra

I use bindfs with osxfuse and sshfs to mount specific folders (chroot) to allow sftp access for external users (macOS Sierra 10.12). Binding a readOnly folder for the user "sftpusr" is done with bindfs -r -u sftpusr /volume/folder /chroot/folder The folder is correctly bound, I can login using sftp and listing the folder once only - then folders and files disappear, I need to mount and bind again. There is no difference in using either homebrew to install osfuse, sshfs, bindfs or making my "own" binaries. I had this feature running for years (Mavericks, Yosemite). Is this an incompatibility with macOS Sierra?
