--- Comment #4 from Florian Meister <f...@sfs.com> --- Thanks for the ultra fast reply :) There are 2 event-streams which are used by the application. https://localhost/api/provide-production-infrastructure/get-live-state-info-multi https://localhost/api/provide-operation-live-info/get-operation-live-info-multi Blocking means that in the chrome developer tools the request is pending. Interestingly _no_ other requests are performed - they are also pending. So it seems that this reqeust is blocking the other ones. When this happens apache stops logging these messages. Because it's encrypted traffic I do not see if the browser is stopping to send requests or if apache is stopping to processing this requests. But it seems apache is stopping to route requests to the backend servers. After about 30 seconds apache is processing the requests again.
