i've written windows service in c# interfaces third party via external web service calls (soap). of calls respond , slowly (for example, quick = retrieving list of currencies; slow = retrieving historical value of currencies per product on many years) the external service works fine when run on local machine - quick calls runs 20 seconds; slow calls runs 30 minutes. can't speed of 3rd party service , don't mind time takes return answer.. my problem when deploy service azure virtual machine: quick call works locally; slow ones never returns anything. have tried exception handling, logging files, logging eventlog. there no clear indication of goes wrong - seems whatever reason - long running web service calls, never return azure. i've read somewhere there sort of connection-recycling happening every 4 minutes, suspect somehow causing external web service response land somewhere in void load balancer or whatever not knowing longer whom requested content.
