shfs crash (4.5.4)

Hi,

I have never used "user shares" before, and last night I decided to try enable them and experiment. Catastrophy!

When I enabled the "user shares", the system automatically created a few dozen shares out of all root folders on the disks. I had to go through all of them and manually set them one by one to "Don't export".  The only thing I left to be exported was (as read-only) one folder -- "videolib".

/mnt/disk1/videolib/

/mnt/disk2/videolib/

There are no duplicate files in my videolib directories.

All was well until I issued one `find` command on the console. It started output some expected results, but then it just hung. Switching to htop on tty2 showed shfs maxing the CPU at 100%. I had the syslog set to output to tty12 so I switched there, and found it going totally berzerk, writing endless entries about duplicate objects, something like this:

etc., etc...

Switching quickly to tty3 I went to /var/log/ and watched the syslog growing really really fast.

Then the whole system crashed.

Now, I know I have duplicate files on different disks, but they are all in directories that are set as "Don't export".

And this whole disaster didn't happened until I issued the seemingly innocent command:

find / -iname "*mover*"

Is that how shfs "normally" behaves?  Can we somehow disable that duplicate object scan?  At least disable it for directories that aren't exported?
