我面临与本文相同的问题。 drupal views module mysql error处理异常时抛出的额外的未捕获异常
我在/opt/lampp/etc/my.cnf的max_allowed_packet增加从1M到60M，但问题仍然出来，当我尝试在结构中添加的一切。这是屏幕代码。
处理异常时引发的附加未捕获异常。
原始
PDOException: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away: SELECT * FROM {uc_product_classes}; Array () in uc_product_class_load() (line 1704 of /opt/lampp/htdocs/advanced-a/sites/all/modules/uc_product/uc_product.module).
附加
PDOException: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away: SELECT ff.* FROM {filter_format} ff WHERE (status = :db_condition_placeholder_0) ORDER BY weight ASC; Array ([:db_condition_placeholder_0] => 1) in filter_formats() (line 407 of /opt/lampp/htdocs/advanced-a/modules/filter/filter.module).
未捕获异常的会话处理程序抛出。
PDOException: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away in _drupal_session_write() (line 206 of /opt/lampp/htdocs/advanced-a/includes/session.inc).
任何帮助将不胜感激。
