Error : 'MySQL server has gone away'

[10NANCY]

Hello!
There is an error in my application : 'MySQL server has gone away'. I wan to fix that error. What can I do now?

There are two main reasons for this error message to show:
# Either the MySQL query you are trying to execute takes too long and the MySQL server times out.
The solution for this issue is to optimize your database for the queries which fail.
# Or you have a crashed table in your database.
The solution in this case is to repair and optimize your database.

There are several reasons for that error, but usually most of the users try to run an query after closing the connection to the server. And this points to a logic error in the application that must be corrected.

Anyway, you need to elaborate what exactly you are doing so we can suggest you an appropriate solution.
