[otrs] Backups

Hi, I'm using /opt/otrs/scripts/backup.pl to backup otrs but for the last few weeks, I've been getting: Backup /home/otrs/backups/2009-11-02_06-00/Config.tar.gz ... done Backup /home/otrs/backups/2009-11-02_06-00/Application.tar.gz ... done Dump MySQL rdbms ... mysqldump: Error 2013: Lost connection to MySQL server during query when dumping table `article_attachment` at row: 5477 failed Compress SQL-file... done Can anyone give me a clue as to what the problem is? If I do a manual mysqldump, it dumps fine. Josh.
