[Samba] Clients loose connection

[Dirk Wagner]

Hi there,

I set up a Samba 3. Server on a SUSE 9.1 box, working as a PDC.
There are Win9X and Win2K Clients connecting to the server.

At a certain time (has been at 1 to 48 hours of uptime), the clients 
loose connection to the server.
At this point, it is not possible to log into the server on a new 
terminal window, but running processes are still running and reacting.

I disconnected the server from the network to see, if some odd 
traffic is causing the problem - but no change in bahavior.

tcpdump shows also nothing striking.

top -i shows 25 entries with smbd:

6065 root 0 8980 3296 7468 D 0.0 0.0 0:00.00 smbd
...
6078 root 0 8980 3296 7468 D 0.0 0.0 0:00.00 smbd

24 times with user root and one time with an other user (the one who 
mentioned the disconnection first)
all the entries were looking like shown above.

At this point, I can end top and tcpdump but halt shows no reaction...
So I have to reboot the server by cuting the power-cord...


I already changed the NIC in the server (from Realtek to 3Com) and 
did the same at one of the clients.
After dooing so, the system was running fine for a longer time, but 
finaly failed also.

Any ideas?

Thanks

Dirk
