Hi Daz ProxySelectorRoutePlanner appears to be the most likely culprit but I cannot spot anything obviously wrong from the logs. My recommendation would be to stop using SystemDefaultHttpClient (it will be deprecated in 4.3 anyway) and apply system settings selectively once by one in order to narrow down possible causes. I'll try to have a closer look at the logs in the coming days.
