説明
We have observed that Envoy with the Connection Limit Filter configured, at some point will report 2**64 active connections for the metric envoy.connection_limit.<listener>.active_connections.
This seems suspicious and could be indicative of some integer overflow.
This did not result in a crash, but did result in some connections being limited when it was not intended.
We configured the filter with a max_connections of 56000 and delay of 500ms
