linux server Creates cache and laravel project gone down

I have stuck in a problem that my laravel project deployed in linux server and server is creating cache in var directory. I run 'yum clean all' command but again creates cache. I run command php artisan cache:clear, php artisan route:clear but no result. is there any way to manage server cache? I face, the error is...

ErrorException in Filesystem.php line 81:
file_put_contents(): Only 0 of 255 bytes written, possibly out of free disk space

my project size is 120 mb.
