IMO, this is a bug: when it can't bind to the port, and thus dies, this should be returned to the start script, so it can report back "FAILED". -Stefan -- BAUR-ITCS UG (haftungsbeschränkt) Geschäftsführer: Stefan Baur Eichenäckerweg 10, 89081 Ulm | Registergericht Ulm, HRB 724364 Fon/Fax 0731 40 34 66-36/-35 | USt-IdNr.: DE268653243
