Cache issue

Hi guys! Meet the new one :)

So the problem is

I have caching part inside my logic and recently i noticed this message in my logs:

filemtime(): stat failed for /var/www/html/console/runtime/cache/e8/e8c57efd78d573551d5fda69694a8d73.bin in file /var/www/html/vendor/yiisoft/yii2/caching/FileCache.php on line 111

Logging inside my code looks like:

if (!empty($result = Yii::$app->cache->get('total_earnings'.Yii::$app->user->id))) {

    return round($result, 2);


//some logic

Yii::$app->cache->set('total_earnings'.Yii::$app->user->id, $result, 3600);

Any suggestions?

Check permissions of cache folder
