I have samba 3.0.10 running on CentOS 3 and it generally speaking works.
But the logs are full of errors

/var/log/messages says:

Does it make any sense to anyone? As I said it works, but only occasionally our foxpro database application crashes on clients workstations. I wonder if it might be related.
