This is a *very* old version, with known major security holes and many
flaws corrected by later 2.2 and more importantly the 3.0 releases of

This means that your reverse DNS is not setup correctly. Later Samba
2.2 versions avoided doing reverse DNS lookups (unless configured), as
most sites cannot configure this correctly.

This issue has been resolved in Samba 3.0, and occurs if smbd processes
die without cleaning up their entries...

This is the correct solution to an 'over-full' sessionid table. This
should not be nearly as much of an issue in Samba 3.0.
