I am getting error in moodle 2.0 like this
"please notify administrator, this problem is most probably caused by small value in max_allowed_packet MySql setting "
Please any one give solution .
You have to do exactly as it says in the error, increase the value for your mysql installation.
The file you need to change might be called /etc/mysql/my.cnf .
In the [mysqld] section, you need to add something like
max_allowed_packet = 16M
