Entries in queue and and process list after fresh install

Hi,

I did a completely fresh install of kaltura (before that I deleted the old folder of kaltura and dropped all tables in the database). When I log in to the kaltura management console and watch the status of the batches, there are entries listed in the queue and process list for some batches (see the attached image). I didn't upload any videos to kaltura yet, so those entries seem a little bit strange. Also when I watch the process list (with "ps") of the server there are no processes listed related to the kaltura batches.

Could the entries be dead processes (or something else) of an earlier installation of kaltura? If so, how can I get rid of the false entries?

Thanks for any help.
