symfony2 - Symfony: Property does not exist - 500 Internal Server Error - ReflectionException -

i removed $hearaboutindustry entity , getting error below in production server, not on local , staging server! thought why or solution?

property tete\adminbundle\entity\customer::$hearaboutindustry not exist 500 internal server error - reflectionexception

config_prod.yml

doctrine: orm: metadata_cache_driver: apc result_cache_driver: apc query_cache_driver: apc

what have solve far:

removed getter , setters entity. deleted whole cache , logs folders , re-created back, inc 777. just in case run cache:clear --env=prod searched hearaboutindustry in directories/files of project. no reference @ all. run doctrine:schema:update. db updated. run doctrine:generate:entities. entity updated. app/console doctrine:cache:clear-metadata app/console doctrine:cache:clear-query app/console doctrine:cache:clear-result

as adam suggested above in comment, improve restart apache if above solutions have been tried , getting no success. solution is:

sudo apachectl graceful
