title: WSO2 API-Manager HTTP Requests terminate after 5mins with Error 101508
body: <p>We deployed a long running HTTP service on WSO2 APIM 3.2.0 that needs approx. 6-15minutes to reply to a request. To support long running HTTP calls we configured the API endpoint timeouts to 15mins and also the APIM in the deployment.toml:</p>
  <pre><code>[synapse_properties]
  'synapse.global_timeout_interval' = 900000
  [passthru_http]
  'http.socket.timeout' = 1000000
  </code></pre>
  <p>However, always after exactly 5 minutes we get the following error:</p>
  <p><code>&lt;am:fault xmlns:am=“http://wso2.org/apimanager”&gt;&lt;am:code&gt;101508&lt;/am:code&gt;&lt;am:type&gt;Status report&lt;/am:type&gt;&lt;am:message&gt;Runtime Error&lt;/am:message&gt;&lt;am:description&gt;Error in Sender&lt;/am:description&gt;&lt;/am:fault&gt;</code></p>
  <p>This indicates that our backend service is terminating the connection. However, if we call the service directly, i.e. without APIM Gateway it replies after 6-15min. Do we miss any timeout settings in APIM that it completes after 5mins ?</p>
  <p>Thanks a lot for your help!</p>
  <p>Cheers,</p>
  <p>Sebastian</p>
