MySQL: MySQL server has gone away

Issue: I need to restore quite big mysql db to local db server using mysql restore command, but got this error.
 ERROR 2006 (HY000) at line XXX: MySQL server has gone away

 SOLUTION: 

1. Stop mysql-server
   # /usr/local/etc/rc.d/mysql-server stop
2. Open file my.cnf in mysql directory 
3. Add this 2 line:
   [mysqldump]
   quick max_allowed_packet = 16M
   
   [mysqld]
   max_allowed_packet=32M
   
   [mysql]
   max_allowed_packet=32M
4. Start mysql-server back
   # /usr/local/etc/rc.d/mysql-server start
5. Try restore the mysql db again
   # mysql -uroot -p --default-character-set=utf8  <  filenamexxxx.sql
   **It works for me. Try it yourself.
