nautilus keeps listing files in smb shares

["Nick Demou (enLogic)" <ndemou enlogic gr>]

In my ubuntu/gnome setup I have mounted some samba shares via smbmount. 
From that moment on whenever I start X, activity on my network starts 
and it never stops until I shutdown X. If I kill-all nautilus then 
activity stops for a second and restarts as soon as nautilus restarts. I 
know very little about the smb protocol but from a quick look at an 
ethereal capture it seems that nautilus keeps listing the contents of my 
samba shares...kind of anoying

Has anybody else noticed anything like this?
