I have just take an image from the request page and immediately restart server.
it has been again.
If a computer get in page on last half an hour it allow to show directory. or it come from cache i could not check for error page at the moment.
please help me why it throttle page ?
or does it log to some where for why it throttle
It doesn't look like Litespeed throttling it.
When it happens again, do following to help troubleshoot:
1. check EAProc WaitQ in Admin CP => Actions => Real-Time Stats
Does that stay in zero? If not, check Max Connections in lsphp5 External App (Admin CP => Configuration => Server => External App => lsphp5) and make sure PHP_LSAPI_CHILDREN environment match it.
2. run 'dmesg' from command line
See if you get anything like 'iptable full'. If so, you need to increase conntrack table size.
3. run 'top' and post the screenshot here.
