Openshift, 503 Service Unavailable. There are no servers available to process this request.

Question

I have a scalable PHP 5.4 cartridge on Openshift with a bronze account. This is a Wordpress blog and I used it up to 2 weeks ago.

Today I returned to visit him, and he says:

503 Service not available. The server is not available to process this request.

To check the status of the proxy server, I visited this link http://myapp-mydomain.rhcloud.com/haproxy-status , and there I see this:

It seems DOWN.

Checking logs with rhc tail I see this line:

==> app-root/logs/haproxy.log <== [ALERT] 077/194638 (138628) : proxy 'express' has no server available! [WARNING] 086/161237 (138628) : Server express/local-gear is DOWN for maintenance.

[ALERT] 086/161325 (33522) : proxy 'express' has no server available! 

I also tried restarting the application using the "restart" button with the opening, but this did not work.

I don’t know how to decide. Any idea?

Answer 1

Your free OpenShift gears are handled by unused processing power / throughput. If the server is currently not available for starting transfers for your application, the request will be rejected using "503 Service Unavailable: the server cannot process this request."

If you want to ensure the uptime of your application, use paid transfers.
