Backup with MySQLDumper failed
 

I have installed the latest Mysqldumper version and when I do a backup I get this error message:

Warning: mysql_query() [function.mysql-query]: Unable to save result set in /var/www/web1/html/mysqldumper/inc/functions_dump.php on line 156
Fatal error: the CREATE-Statement of table 'vb_picturecomment' in database 'usr_1' couldn't be read!: MySQL server has gone away

Does anybody know what is going wrong here?
