Hi Bastien, I've got a problem that looks a bit like yours. My error message: [Wed Sep 30 08:28:54 2009][Error][Kernel::System::Ticket::TicketNumberLookup][637] Cannot allocate statement when disconnected from the database, SQL: 'SELECT tn FROM ticket WHERE id = ?' I haven't found any hints to solve this issue, yet. Are you using MSQL, too? Timo Von: otrs-bounces@otrs.org [mailto:otrs-bounces@otrs.org] Im Auftrag von Bastien Leblanc Gesendet: Mittwoch, 30.

Betreff: [otrs] Error Kernel::System::Ticket::TicketNumberLookup ERROR Database disconnected Hi, I get a lot of these errors in the log file, but all seem to be running fine: [Wed Sep 30 14:35:24 2009][Error][Kernel::System::Ticket::TicketNumberLookup][637] ERROR Database disconnected, SQL: 'SELECT tn FROM ticket WHERE id = ?' Any idea of what is the problem? Bastien.
