No.  The presence of .pck files means (a) some runner is behind in its
work but will eventually get to them, (b) some runner is waiting for
human intervention (moderations), or (c) some runner isn't running.
Depending on the name and the directory where found, they correspond
to different runners.

To find out if the bounce runner is running you use ps from the
command line on the Mailman host.  On Linux, the command

    ps ax | grep BounceRunner

will find it.  If that command produces output, it's running (actually
you need to check the status in the third column, if it's S or R the
process is normal, if it's Z or T something bad has happened).
