Bug#466138: lvm2 file descriptors open

Package: lvm2
Version: 2.02.39-7
Followup-For: Bug #466138

I think this is the same kind of issue as in the previous report, though I'm not sure.

>From Jan 5th on a nightly cron job that creates snapshots produces
messages like this for every lvcreate:
+ lvcreate -L10G -s -n _home /dev/daisy/home
File descriptor 3 left open
File descriptor 41 left open
File descriptor 42 left open
File descriptor 43 left open
  Logical volume "_home" created
The same file descriptors are listed for each group.  I do not see
such messages when I do other commands such as lvs.

The only installs in the previous day were of a locally built,
backported (from sid--I'm on lenny) samba.  These did require
upgrading libpam0g, libpamruntime, libpam-modules to sid,
and installing libdb4.7 from sid. I also upgraded man-db and doc-base
within lenny.

I think the previous discussion implies 
a) my lvcreate's are still working OK and
b) I may have a security problem with some other program.  The new
installs would be the obvious suspects, particularly pam.

I'm looking for confirmation of a) and advice on how to handle b).

P.S. It might also be relevant that I get a parse error from lvm every
time the system starts, at something like byte 3200.  I seem to have
all my volumes, and I don't know where the data is that is being read.
