clafff Posted September 17, 2008 Share Posted September 17, 2008 I manage several apache 2.2 + php servers. When there is heavy traffic a lot of GET request got a 503 error code. The POST request does not. How is this possible ? More, I got these 503 errors but there are cpu, memory and http slots left, so I don't understant why I got these errors. Does someone has a hint ?

corbin Posted September 18, 2008 Share Posted September 18, 2008 Is there anything in the Apache error log around when it happens? Link to comment https://forums.phpfreaks.com/topic/124654-apache-503-errors/#findComment-644414 Share on other sites More sharing options...
clafff Posted September 18, 2008 Author Share Posted September 18, 2008 nothing special in the logs. for example I have a cron script that calls a stat page on every server. If the script use a GET request, there are numerous 503 errors when a server is a little loaded. If it uses a POST request to retrieve the data, there are no errors. I would like to know exactly what this 503 error mean, no cpu left, request queue filled, ... ?
