Bug Description
Binary package hint: samba
I've set up a samba usershare in ubuntu 9.04 using samba 2:3.3.2-1ubuntu3.1
[snip]
cat /var/lib/
#VERSION 2
path=/home/
comment=
usershare_
guest_ok=n
[snap]
which _IS_ working as I can write/read files on it. I have a visual studio source project hosted there. Every few minutes a "data loss on write" message appears in windows. It is always affecting the projects .ncb file. Each time this message appears the following lines appear in /var/log/

I've tried to debug it further but was unable to obtain a coredump / attach a debugger. The "Permission denied" messages appears a few times when samba recorvers (sometimes just once, sometimes 3 times - I suspect some race here?).

When activating [homes] and accessing the files through this share no data loss on write errors occure on the visual studio side. Also the speed when accessing the files is increased. The bug seems to be in the usershare mechanism.
