Depending on your OS and installation places may vary (in a Typical Linux server it would be /var/log/apache2/[access|error].log). Having a 503 error in Apache usually means the proxied page/service is not available. I assume you're using tomcat and that means tomcat is either not responding to apache (timeout?) or not even available (down? crashed?). So chances are that it's a configuration error in the way to connect apache and tomcat or an application inside tomcat that is not even sending a response for apache. Sometimes, in production servers, it can as well be that you get too much traffic for the tomcat server, apache handle more request than the proxyied service (tomcat) can accept so the backend became unavailable. share|improve this answer edited Jan 30 '14 at 13:28 answered Jun 11 '11 at 19:25 regilero 19.1k23377 so the summary is that the servlet container maybe got out of memory because of traffic, right ? –MahmoudS Jun 11 '11 at 23:04 can be that, can be as well a lot of other things :-) but you can see it at least as a message from apache telling you tomcat is not responding/available. –regilero Jun 12 '11 at 7:58 add a comment| Your Answer
that this is a temporary condition which will be alleviated after some delay. Some servers in this state may also simply refuse the socket connection, in which case a http error 503 blackberry different error may be generated because the socket creation timed out. Fixing 503

It is still functioning minimally because it can at least respond http error 503 the service is unavailable iis7 with a 503 status code, but full service is impossible i.e. the Web site is simply unavailable. There are a myriad possible reasons for this, but generally it is because of some human http://stackoverflow.com/questions/6299086/how-to-detect-cause-of-503-service-temporarily-unavailable-error-and-handle-it intervention by the operators of the Web server machine.

This lookup (conversion of IP name to IP address) is provided by domain name servers (DNSs). Open an IP socket connection to that IP address. Write an HTTP data stream through that socket. Receive an HTTP data stream back from the Web server in response. This data stream contains status codes whose values are determined by the HTTP protocol. Parse this data stream for status codes and other useful information. This error occurs in the final step above when the client receives an HTTP status code that it recognises as '503'.

When you put Drupal in maintenance mode, it serves this error to anyone who is not already logged in with sufficient rights.
customer that got a 1 minute timeout when restarting their DJango webapp, claiming that Apache did get stuck. After a test, in the Apache log files we found: [Thu Oct 11 09:35:18 2012] [error] (111)Connection refused: proxy: HTTP: attempt to connect to 192.168.0.10:48880 (192.168.0.10) failed [Thu Oct 11 09:35:18 2012] [error] ap_proxy_connect_backend disabling worker for (192.168.0.10) [Thu Oct 11 09:35:19 2012] [error] proxy: HTTP: disabled connection for (192.168.0.10) [...] The problem is that the Apache proxy module, recognising that the service was unavailable, stopped redirecting requests to it for one minute. The problem was solved adding a retry=0 parameter to the ProxyPass directive: ProxyPass / http://192.168.0.10:48880/ retry=0 timeout=5 ProxyPassReverse / http://192.168.0.10:48880/ References: Apache mod_proxy documentation, Serverfault.com tip.

Without retry=0, I'd have to wait up to a minute before being able to access my dev site through the proxy if I attempted to access it without starting up the dev machine… Reply ↓ Colin McDermott (@colinmcdermott) on 21 September 2013 at 4:52 pm said: Just wanted to say a big thanks. We were having a big problem with a reverse proxy intermittently not working. Your post was a huge help. Incidentally, dropping the timeout=x really was better for us. Thanks!
