[Samba] Problems with nmbd (samba 3.0.10)

[Thomas Schaefer]

Hi,

I've installed a samba 3.0.10 (configured with --enable-cups,
--withsmbmount, --with-acl-support) on a standard SUSE Linux
9.2-Distribution with Kernel 2.6.8-24.10-smp.

The Samba-Server works as PDC since a month now and does it fine. But
one big problem still exists:
After about 10-20 hours after the start of smb+nmb the nmbd stops working.
The symtoms are:
No new users can login into the NT-Domain
but users who already logged in can still access the shares

Swat shows that the nmbd is not running (smbd and winbindd are still
running)
But the process-list from linux still shows that several
"/usr/local/samba/sbin/nmbd -D" are still runnung

After killing the nmbd and restarting the nmbd everything runs fine
again - for about 10-20 hours...

Any help would be appreciated. (If it helps I could post the smb.conf too)

Thanks,
	Tom

Here is a example from the log.nmbd-file of that time from start until
crash and the next start:
