Admin UI - Collection reload leads to infinite loop

Reloading a collection takes about 15s for us. If we use the reload button in collections admin ui the server ends in an infinite loop of reloading requests.
We checked the browser traffic and every 10 seconds the reload requests ends in Status "cancelled" due to a timeout and a new reload request is triggered. If the reloading takes above 10s it will always end in an infinite loop.

We checked the angular files of solr and inspected this part to be responsible for the 10s timeout:

file: /js/angular/app.js

.factory('httpInterceptor', function($q, $rootScope, $timeout, $injector)

{ var activeRequests = 0; ... activeRequests++; config.timeout = 10000; return config || $q.when(config); }

;
