Hi guys!

I've a weird problem. I've mysql 5.1 installed on my ubuntu 9.04.

I've used it a long time (say 3 month) and everything was going right. Until i faced this really weird problem.

When i want to connect to a random database i get this message:

ERROR 2006 (HY000): MySQL server has gone away No connection. Trying to reconnect... Connection id: 1 Current database: test_cake

ERROR 2006 (HY000): MySQL server has gone away No connection. Trying to reconnect... ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111) ERROR: Can't connect to the server

It only happens with some databases, while others are totally usefull and healthy. After that, if i try to restart the server i get this.

shell> /etc/init.d/mysql restart * Stopping MySQL database server mysqld cat: /var/run/mysqld/mysqld.pid: Permiso denegado [fail] * Starting MySQL database server mysqld cat: /var/run/mysqld/mysqld.pid: Permiso denegado cat: /var/run/mysqld/mysqld.pid: Permiso denegado cat: /var/run/mysqld/mysqld.pid: Permiso denegado cat: /var/run/mysqld/mysqld.pid: Permiso denegado cat: /var/run/mysqld/mysqld.pid: Permiso denegado cat: /var/run/mysqld/mysqld.pid: Permiso denegado cat: /var/run/mysqld/mysqld.pid: Permiso denegado cat: /var/run/mysqld/mysqld.pid: Permiso denegado cat: /var/run/mysqld/mysqld.pid: Permiso denegado cat: /var/run/mysqld/mysqld.pid: Permiso denegado cat: /var/run/mysqld/mysqld.pid: Permiso denegado cat: /var/run/mysqld/mysqld.pid: Permiso denegado cat: /var/run/mysqld/mysqld.pid: Permiso denegado cat: /var/run/mysqld/mysqld.pid: Permiso denegado cat: /var/run/mysqld/mysqld.pid: Permiso denegado cat: /var/run/mysqld/mysqld.pid: Permiso denegado [fail] ("permiso denegado" is "permission denied").

I don't know what to do. I change the /var/run/mysqld/mysqld.pid attributes but still not working.

Can anybody help me ?
