- a source's interval must be greater than 0: a source is turned off with enabled, not with a zero interval, so JSCSourcesSource rejects an interval of 0 or less (its validate is promoted to each source's section); - max_message_size rejects -1: JSCServerWebSocket rejects a max_message_size of -1 (util.ByteSizeNoLimit), as a client could then exhaust the server's memory; - every setting documents what 0 or empty means (zero/none, no limit or a default).
