Mac OS X 10.4: Restart or shutdown delay if AFP volume is mounted but server may not be contacted.

Issue or symptom

If an AFP volume is mounted, but the server becomes unavailable and cannot be contacted, significant delays may occur when trying to shut down or restart the computer.

Solution

As a workaround, unmount any AFP volumes before restarting or shutting down. If volumes were not unmounted, wait until Mac OS X completes the AFP timeout.

If you have waited a considerable amount of time, you can force restart the computer:

• Hold the computer's power button until it turns off.
  
  
• Advanced option: If ssh is enabled on the computer, try to ssh into the affected system with an administrator account and perform the following command to force restart: sudo reboot
