Hi pound people,
We have a pound server which is serving up to two load balancers at Amazon - we are monitoring with icinga. We have noticed the "503 Service Unavailable: Back-end server is at capacity " message showing up in icinga. It appears that this is from pound. If so how does pound determine this situation? Since there are two backend servers is it the situation that an existing session which is connected to one of the backend servers is not able to communicate with the backend server? If not why does pound not direct to the other load balancer? Any insite on how to prevent these events would be appreciated. johnh...
