Please upload your smb.conf and an ls -la of your usershare directory.

and smb.conf:

Comment 3 Karolin Seeger 2009-12-29 04:05:46 UTC
Usershares need to be enabled by setting "usershare max shares = x". I don't see this parameter in the smb.conf. Does 'net usershare add testshare /home/test Testshare' work (after creating /home/test with owner "test")?
Comment 4 Karolin Seeger 2009-12-29 04:10:37 UTC
And please retry after setting "allocation roundup size = 0" for the Visual Studio share.
Comment 5 Volker Lendecke 2010-02-08 02:49:50 UTC
Please upload a debug level 10 log of this crash. If possible, can you run smbd under valgrind please for a test (it slows down smbd a LOT) and upload the output here?

Thanks,

Volker

I resolve why it works at all:

Unfortunatly ubuntu has an very misleading patch integrated which changes the default from
usershare max shares = 0 to 
usershare max shares = 100 

I will ask them to revoke this patch since it seems both dangerous and unneccesary to me.

But nevertheless something very weird does happen here ...

No feedback in almost half a year. Closing.
