Errore importazione database da remoto a locale

Ciao a tutti,
mentre tentavo di importare un databse per aggiornare il core in locale ho ottenuto una serie di errori che riporto:

Additional uncaught exception thrown while handling exception.

Original

PDOException: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away: SELECT s.lid, t.translation, s.version FROM {locales_source} s LEFT JOIN {locales_target} t ON s.lid = t.lid AND t.language = :language WHERE s.source = :source AND s.context = :context AND s.textgroup = 'default'; Array ( [:language] => it [:source] => Access will be granted to users viewing their own signup list or with the 'view all signups' permission. [:context] => ) in locale() (line 720 of /Users/lucasanna/Sites/PREMIOARTE-locale/modules/locale/locale.module).

Questo è cio che vedo quando mi collego al sito dopo aver importato il database dal sito online che funziona correttamente, ma che non posso aggiornare!

Qualcuno sà perchè non vedo il sito?

Grazie a tutti!
