HHVMでエラーログからnoticeを外したい

環境
Centos7.2.1511
HipHop VM 3.15.0
nginx version: nginx/1.11.6

HHVMが吐き出すエラーログ「/etc/hhvm/php.ini」からnoticeは非表示にしたいのですが
error_reporting = E_ALL & ~E_NOTICE
hhvm.log.level = Warning
hhvm.log.runtime_error_reporting_level = 8183
ここらへんを設定しhhvmをrestartしてもnoticeが表示されてしまいます。

他に設定する方法があるのかどうかご教示いただけないでしょうか。
