A wamd connection to MySQL timed out, causing a message containing "MySQL server has gone away" to be logged.
When wamd notices the closed connection, it will open a new one to MySQL. It is possible that this failure will cause a distortion in the presented statistical data until such time as the next attempt is made to perform the operation.
If wamd's MySQL connection sits idle longer than the configured timeout value, MySQL will close that connection.
As an administrator, log on to MySQL and change the server parameter that controls the number-of-seconds timeout value using the following MySQL command: set global wait_timeout=28800. (Note: 28800 seconds is 8 hours, and is the MySQL default. Your value may differ.) Alternatively, the MySQL global wait_timeout value can be set on the command line in the init.d startup file. Although you can increase MySQL's timeout value, for the most part, it isn't necessary.
