[imp] weird problem

[Michael Geier]

Since last night (with absolutely no changes to the webserver, php
installation or horde 2.1/imp 3.1 installation) , deleting less than all
messages in mailbox emptys mailbox...

ie.  3 message, delete 1, all gone

Server:
        RedHat 7.3
        QPopper 4.0.4
        Apache 1.3.27   (--prefix=/path --enable-module=so)
        php 4.2.3       (--with-apxs=/path/bin/apxs --with-imap
                         --with-mysql --with-esoob --with-pear
                         --enable-ftp --with-gettext --with-xml)

The only thing that has changed on the server recently is an updated
version of xinetd was released last night (however the "init" script for
pop3 did not change)

xinetd.d/pop3
        service pop3
        {
                disable = no
                socket_type     = stream
                protocol        = tcp
                wait            = no
                user            = root
                server          = /usr/local/sbin/popper
                server_args     = -sR
        }

No log entries are being produced except the login/logout msgs.
Any thoughts on where to begin to look appreciated.
