Urgent! How to stop a running publication

Hello all

We're on CCM 2.0 (still with SP03).

We have several CATALOG_PUBLICATION_REQUEST jobs running and stopping again immediately with 1 single error message (in SLG1) telling us that the publication of our master catalogue will again be scheduled in 15 minutes.

We stopped / deleted all those scheduled jobs because it didn't come to an end else.

Now when trying to publish the catalog, regardless whether initially or only delta/differences or even when trying to cancel the publication request the system tells us that there is already a publication in process.

Now how to set the system status back so that publication attempts can run again properly?!?

TIA
