Bei zu grossen Log_Log und/oder Change_Change Tabellen kann es vorkommen, dass die Datenbankverbindung in ein Timeout läuft und die Installation damit abbricht.

Ein Workaround ist folgendes:

• Log_Log Tabelle truncaten

• Manuell dieses SQL-Skript einspielen und zuvor die Timeouts im MySQL Workbench erhöhen:
  

  Code Block
  language sql
