I've had various levels of luck with ejabberd and load balancers; I
have not used ELB.
Most load balancers worked just fine, with differences in performance.
I had some issues with HAProxy 1.13.x (haven't tried 1.14.x), where no
amount of configuration of timeouts (client->haproxy, haproxy->server,
or full client->server) seemed to allow the connection to remain up
reliably. You may be having a similar situation -- while the balancer
supports generic TCP connections, it may be inherently for or
tuned-for mostly short lived HTTP connections.
