help please : ERROR 2006: MySQL server has gone away

[Marois, David]

Hi,
I have this error when I am connected in mysql:
 
ERROR 2006: MySQL server has gone away. No connection. Trying to reconnect...
 
I only did this command: show databases;
and received the error.
 
I noticed that if I don't send a command since 25 sec, I have the error.
 
Also, my variable wait_timeout = 3600.
 
Any ideas ?
