Extremely Slow (Session::open)

Hi All,

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?



Check overall server load from console with top or htop. Looks like it’s heavy.

Hi samdark,

Thanks for your help. I was able to run top but from what I could tell the server was not under stress or heavy load. Although I am new to top and there is a chance that I was interpreting it wrong.

The interesting part is that I have not experienced that condition anymore. So, it could be a heavy load as you stated but temporary and intermittent.

Thanks again.
