I am having trouble with a recently deployed yii app. It’s been working fine until today. My debugger shows very long DB queries, which I am looking into. In addition, some requests are taking for ever when the DB queries are not the issue. Here is a snippet of the debugger info showing a Session::open that took over 5 minutes (if I read the log correctly).
Time Since Previous Level Category Message
14:46:04.401 5m 32s 882ms info yii\web\Session::open Session started
Any idea what could be causing this issue?
