Hello,

We've been using LSWS for a few years and we are familiar with 503 errors, but random 503 errors have become too annoying recently. It occurs when the server load averages are too high. I believe it's the normal behavior to display a 503 error message when the server couldn't handle the process. The weird thing is the server load averages go higher even there is no huge traffic. This happens 3-4 times in a day and the pages can not be displayed with a 503 error message for 5 to 30 minutes.

Can you please tell me which details i should specify so you can help me?

above is a complete error log for 503 error happening at 03:41:47, which extracted from error.log.

please check if your recent 503 error has same pattern as above: before "Max retries has been reached, 503!", there is a line like
"connection to [/tmp/lshttpd/lsphp5.sock.226] on request #0, confirmed, 0, associated process: -1, running: 0, error: Connection reset by peer!"

above log is extracted from a server which just upgraded to 4.1.11 recently, and all are same pattern(on request #0, confirmed, 0, associated process: -1).
