This is what I see in log file when changing user via fast user switching:

kernel[0]: AFP_VFS afpfs_unmount: /Volumes/****

kernel[0]: AFP_VFS afpfs_unmount : We are the last mnt/sbmnt using volume /Volumes/*****

kernel[0]: AFP_VFS afpfs_unmount : We are the last volume using socket /Volumes/*****

kernel[0]: AFP_VFS afpfs_unmount : afpfs_DoReconnect sent signal for unmount to proceed

Anyone found a way to change this behavior

I have exactly the same problem, as a work around I have created a script that will re-mount the drives.

yep, the same problem here, but without user switching.

I have updated a lion server to mountain lion and are now experiencing disconnections on all users.

PS: The update is some kinda awkward. First update the the 10.7.4 Server to 10.8 Client, than install the Server.app and make it a server again. I am not sure, if this is a good thing... and VPN is broken too, and I am missing the firewall. I do not want to fummle around with terminal to edit my extensive rules I made... ;-(

This question is answered here. It solved my afp-disconnect problem.

I dont think tis is the same problem,

As far as I can tell the https://discussions.apple.com/thread/4140142?answerId=19086127022#19086127022 discussion is about local volumes (via firewire, USB) unmounting.

I tryed:

sudo defaults write /Library/Preferences/SystemConfiguration/autodiskmount AutomountDisksWithoutUserLogin -bool YES

but it made no diffrens in my AFP volume problem. :-(

Did you reboot after the terminal command? I have the same situation here... External FW-Drives and lots of shares on it.

Yes, I did a reboot.

My problem is NOT on OS X server. (I never logout from my admin account or use fast user switching on my server)

My problem is on OS X Client with mounted AFP volumes (not USB or FireWire harddrives)

* Lion Client with mounted AFP volume(s) from Lion Sever = remains mounted when using fast user switching

* Lion Client with mounted AFP volume(s) from Mountain Lion Sever = remains mounted when using fast user switching

* Mountain Lion Client with mounted AFP volume(s) from Lion Sever = Unmount when using fast user switching

* Mountain Lion Client with mounted AFP volume(s) from Mountain Lion Sever = Unmount when using fast user switching

In my case it´s a problem on with Mountain Lion Client.

I too have exactly the same issue. It is certainly a bug in Mountain Lion and I've logged it with Apple.

The only "fix" I can find if you want to keep running Mountain Lion is to stop using AFS and use SMB until the bug is resolved.

I dislike SMB as the network performance is 50% slower than AFS.

I have this problem too. My iMac is connected via ethernet to a QNAP NAS, and whenever I lock the computer, all AFP shares are unmounted. Upon unlocking, the shares have to be manually mounted again. For people who keep their iTunes library on a network share, this must be particularly frustrating. That's not the case for me, but I do need access to other files and resources stored on the NAS, so I depend on keeping my AFP mounts alive even when I lock my computer.

This never happened under Lion or Snow Leopard. Hopefully this is a bug.

Thanks Apple! :-)

noben,

Was there anything else that could have resolved your issue? I'm on 10.8.3 and have a AFP Volume that removes itself every few minutes. It's driving me crazy. I also see the same logs as you in Console. Any help you could give me would be immensely appreciated. Especially since this is my CEO's iMac. :'-(

No, dont think so. 10.8.2 solved my problem on two computers.
