mysql keeping crashings on my drupal site
PDOException: SQLSTATE[HY000]  Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111) in lock_may_be_available() (line 167 of /var/www/is373/vector/includes/lock.inc). I keep on getting this on my drupal site. To fix it temporarily, I have to restart apache2 and then mysql. Getting tired of doing this and getting interrupted.
