[SR-Users] What could cause an intermittent fault (28) with http_query()?

[Brandon Armstead]

What happens if you run the daemon in foreground / high verbosity ?  Paste error logs back here.  My guess would be there is some kind of blocking happening, ie DNS lookup possibly try using an alternate resolver ?
