Exceeded configured max-open-requests value

[tbenst]

Thanks for this! Just tried using the docker command in README. I verified that I can see Cromwell Swagger on localhost:8080, but when trying to connect using cromwell-client I get: running workflow at http://127.0.0.1:8080 failed Exceeded configured max-open-requests value of [32]. This means that the request queue of this pool (HostConnectionPoolSetup(127.0.0.1,8080,ConnectionPoolSetup(ConnectionPoolSettings(512,0,5,32,1,Duration.Inf,100 milliseconds,2 minutes,30 seconds,ClientConnectionSettings(Some(User-Agent: akka-http/10.1.11),30 seconds,2 minutes,512,None,WebSocketSettings(<function0>,ping,Duration.Inf,akka.http.impl.settings.WebSocketSettingsImpl$$$Lambda$153/1984513847@29dfcd54),List(),ParserSettings(2048,16,64,64,8192,64,8388608,8388608,256,1048576,Strict,RFC6265,true,Set(),Full,Error,Map(If-Range -> 0, If-Modified-Since -> 0, If-Unmodified-Since -> 0, default -> 12, Content-MD5 -> 0, Date -> 0, If-Match -> 0, If-None-Match -> 0, User-Agent -> 32),false,true,akka.util.ConstantFun$$$Lambda$42/1795960102@39d055a7,akka.util.ConstantFun$$$Lambda$42/1795960102@39d055a7,akka.util.ConstantFun$$$Lambda$43/1027591600@74f495e4),None,TCPTransport),New,1 second),akka.http.scaladsl.HttpConnectionContext$@277f2c96,akka.event.MarkerLoggingAdapter@354212da))) has completely filled up because the pool currently does not process requests fast enough to handle the incoming request load. Please retry the request later. See http://doc.akka.io/docs/akka-http/current/scala/http/client-side/pool-overflow.html for more information. Let me know how I can help debug?
