Network Manager Disconnects after 4- 5 hours

Hi all,

i have a strange problem with my suse 11,
the network manager disconnects me automatically after a given amount of time.
This didn’t happen with 10.3!

I have a wired connection (eth) on a desktop running kde and gnome…
Also i noticed that it happens more often when downloading files.
The only messages i get before the disconnect are…

–>…
dhclient: DHCPREQUEST on eth0 to 192.168.1.1 port 67
dhclient: DHCPREQUEST on eth0 to 192.168.1.1 port 67
dhclient: DHCPACK from 192.168.1.1
dhclient: bound to x.x.x.x(previous ip) – renewal in 26 seconds.
dhclient: caught deadly SIGTERM
dhclient: could not restore resolv.conf: No such file or directory

Anyone, any help? How can i stop this from happening all the time.
