Program is using a deleted file warnings (tiger)

[Ross Boylan <RossBoylan@stanfordalumni.org>]

Tiger is giving me lots of reports like
OLD: --WARN-- [kis012w] Program apcupsd (pid 32630, parent 32628) is using a deleted file: 22188
+/lib/libc-2.3.2.so.dpkg-new
OLD: --WARN-- [kis012w] Program apcupsd (pid 32630, parent 32628) is using a deleted file: 86 983
+/var/log/apcupsd.events.1 (deleted)

Most of the concern libraries with .dpkg-new

This looks as if it has something to do with how dpkg does upgrades,
but I'm a little puzzled that the warnings concern dpkg-new files.
And apcupsd.events.1 doesn't fit that pattern.  I know that logrotate
moves and renames files as it goes, but why is apcupsd writing to
anything other than the current log file?

Thanks.
