Hi,

Ok, the failover problem is solved after I applied Maxim's suggestions.

Now the current problem is that nginx does not load balance equally between servers.

Under heavy load(300 clients) I killed 2 apache servers so apache3 was taking all the load. I put back online apache2 and now for some reason apache3 was getting few hits and most of the load was going to apache2. When I put back online apache1, it got most of the load, apache2 taking less load and apache3 almost no load at all.

Why the strange behavior? How do I make it load balance equally between the 3 apache servers? All the apache servers have identical hardware and software configuration.

Please help
