Hi Claire,

Thanks for your clarifications.

So this seems to be a very simple clustering scenario, where the request dispatching is fully delegated to the load balancer. Is it possible that the balancer fails to guarantee stickiness based on IP address (perhaps the client IP addresses are changeable)?

We could understand this by comparing the logs for both the servers, to see if a session originated in one server is wrongly bound to the other server on subsequent requests.

Please contact support@lightstreamer.com.

Cheers,
