Error when clearing cache for a database.user Apache Env

[PierreB]

Hi everyone,

I receive this error :
[Symfony\Component\DependencyInjection\Exception\ParameterNotFoundException]
You have requested a non-existent parameter "database.user".

When I clear my cache with php app/console cache:clear

The database.user is set in the apache Env, and works well if I clear the cache with a $ rm -R app/cache/*

Any ideas please ?

Regards,

Pierre
