We use HAProxy to balance the load between hundreds of servers, however, there is an issue which is new for us and unexpected (works in any HAProxy version). When number of servers in some backend exceeds 100, all weights for active servers are set to zero (marked as SOFT STOPPED) and backend goes down. The only way to make backend UP again is to set server count to 100 or less. We may need to run hundreds of servers under one backed and distribute the load. How we can adjust this number?
