Error Concurrent connection limit

[Rodrigo Gutierrez]

Hello

I need your collaboration if you can give it to me, I am doing load tests .. I have the configuration of a serviceproxy for REST services and when the number of more than 32 concurrent requests on the membrane arrives, an http 429 appears. In the memroute.log it appears HttpEndpointListener: 130 - Concurrent connection limit reached for IP: and Connection to ip: 9322 refused. No matter what configuration you use. (only target, load balancer  robinroundRobinStrategy, load balancer byThreadStrategy ) after 32 requests it stops responding. I have tried with versions 4.6 to 4.7.3 the result is the same in all.

I appreciate if possible you can help me or tell me if there is a configuration parameter that allows increasing the number of membrane requests

Hi Rodrigo,

using

<transport concurrentConnectionLimitPerIp="60" ...>...</transport>

you can adjust the limit of TCP connections Membrane Service Proxy accepts for incoming HTTP requests. (Note that " target, load balancer  robinroundRobinStrategy, load balancer byThreadStrategy" all refer to logic concerning outgoing HTTP requests.)

This is documented in http://membrane-soa.org/service-proxy-doc/4.7/configuration/reference/transport.htm .

Please refer to conf/proxies-full-sample.xml or https://github.com/membrane/service-proxy/blob/master/distribution/router/conf/proxies-full-sample.xml on how to include <transport> into your configuration (and copy all sub-elements from there), if your proxies.xml does not already include it.

Best, Tobias
