hello, I’m back again, after our testing, The problem is due to rotateFiles and concurrency

config

'log' => [
	'targets' => [
		[
			'class' => 'yii\log\FileTarget',
			'categories' => ['open'],
			'logVars' => [],
			'maxFileSize' => 100, //for better display of errors
			'maxLogFiles' => 5,
			'logFile' => '@root/runtime/logs/open.log',
		]
	],
],

code

$request = Yii::$app->request;
$header = $request->getHeaders();
$get = $request->get();
$body = $request->bodyParams;
$method =  $request->method;
Yii::info([
	'header' => $header,
	'get' => $get,
	'body' => $body,
	'method' => $method,
], 'open');

test with ab

ab -n1000 -c10 http://example.com/path1/path2

You will see that some logs are very small

By the way, I don’t think it’s a good idea to attach an application log when logvar is not empty, preferably something that can be controlled.

'logVars' => ['_GET', '_POST'],

// will hava
... category: application ....
