Network shares unmount during file transfer

[nonoitall]

Binary package hint: gvfs

I've experienced this problem in new installations of Hardy, Intrepid and now Jaunty as well.

I can browse to a Windows network share by going to Places->Network. Then I copy a number of files/directories (totaling ~30GB or so) to a local destination. I expect the transfer to take 1-1/2 to 2 hours on our network. However after a certain amount of time of successfully transferring files (time varies anywhere from less than 5 minutes to half an hour) the transfer hangs, not progressing at all, due to the share having become unmounted. (And the only way to cancel the transfer is to log out, as the cancel button does not work.)

File transfers from manually mounted shares work fine, but using the 'user-friendly' method always hangs.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:

 * Is this reproducible?
 * If so, what specific steps should we take to recreate this bug?

 This will help us to find and resolve the problem.

* Yes, I've attempted such a transfer several times and each time has always gotten hung up at some point. To my knowledge, I've never had a transfer of such a size complete normally - I must either copy the files in smaller groups, or manually mount the share from the command line in order to transfer everything at once.

* Ultimately I'm not aware of anything special I did to trigger the hang. I just browsed to a Windows network share (this one happens to be hosted on Windows XP, but I will check to see if the same thing occurs on shares hosted by other OS's) via Places->Network and attempted to copy a large amount of data to a local directory. After some time (I've never seen a transfer successfully continue past 45 minutes (or roughly 20GB with our network speed)) the transfer will just hang, not making any progress and impossible to cancel without logging out. Further investigation reveals that the share is no longer mounted in ~/.gvfs.

I've checked other distros to see if this is a generic problem, but not even Debian has had this issue when transferring the same files from the same share, so this appears to be unique to Ubuntu.

could be that gvfs-fuse-daemon is crashing, debian is not using gvfs yet if you tried on lenny so not a surprise that it behaves differently, to debug by somebody having the issue I can't confirm the bug and we got no other bugs about this issue

I was just trying out Fedora 11 and discovered this problem is present there as well. Probably not a huge help, but perhaps it will help a little to narrow things down.

To add another affected distro to the list, Arch shows the same symptoms. I'm starting to think I may have just gotten lucky when I tried it with Debian, since I did manage to copy the files successfully with Arch in a previous attempt.

The issue is an upstream one and it would be nice if somebody having it could send the bug the to the people writting the software (https://wiki.ubuntu.com/Bugs/Upstream/GNOME)
