open-vm-tools copy/paste stops working?

edit

A clean installation of Fedora 23 as a VM within a VMWare Fusion (OSX) host results in the inclusion of open-vm-tools. Features such as screen resizing, and copy/paste work perfectly out of the box. However, after some time, the copy/paste sharing between host and guest stop working. Is there a known way to troubleshoot this? So far I have:

• uninstalled and re-installed open-vm-tools using dnf
• restarted the guest Fedora 23 os
• restarted the host OS
• checked and unchecked the "isolation" copy/paste and drag/drop options in VMWare Fusion

However, the inability to copy/paste between guest and host persists. Note that on the same host machine, copy/paste between other VMs, including another fresh Fedora 23 VM, works as expected.
