Memory leak in 2.0.7?

[William R. Knox]

Well, I got one response (included below with my original posting), and
I am now having the problem 13 hours after I stopped and restarted the
samba processes, so I thought I might post again, and send the message
to the samba-bugs address as well. In this case, after 13 hours, my smbd
processes were up to 18 M in size, 16-17 M of which was resident. Does
anyone have any idea what may be going on here? Other details are in the
original message below, and I'll repeat the most basic here:

samba 2.0.7, built with gcc 2.8.1 on Solaris 2.6, running almost
exclusively as a print server.

ANY ideas on what I might be able to do to prevent this would be
appreciated. I am already stopping and starting the services once a day
to try to keep them in line, but that suddenly seems to no longer be
enough. Thanks in advance for any help you can give!
