Dear friend,

The content of /etc/redhat-release :
Red Hat Linux Advanced Server release 2.1AS (Pensacola)

The versions of kernel and samba are 2.4.9 and 2.2.1a respectively.

Please help me find what causes the error messages? Is it serious for
the system ? How do I solve the problem?

Thanks a lot!


Best Regards.
