Probleme MAMP Mountain Lion

bonjour

voila depuis un moment quand j'active les services de MAMP (apache et Mysql )
Mysql ce ferme au bout de 2-3 min et il est impossible de le redémarrer.

voici une partie du log d'erreur :

InnoDB: Check that you do not already have another mysqld process
InnoDB: using the same InnoDB data or log files.
InnoDB: Unable to lock ./ibdata1, error: 35

130606 20:31:21 InnoDB: in this failed attempt. InnoDB only wrote those files full of
130606 20:31:21 InnoDB: zeros, but did not yet use them in any way. But be careful: do not
130606 20:31:21 InnoDB: remove old data files which contain your precious data!

est ce que quelqu'un a déjà résolut de ce problème pour de bon ?

Merci d'avance.
