Can you try Samba 3.0.20a?  A possible (but not verified) explanation is
that connections are not being marked as idle in winbindd, when perhaps
they should be.  Otherwise, make sure to file this on

(Winbindd had a major rewrite in 3.0.20, and the a release cleans up a
number of issues found in the field).
