what i wanted to see was if the problem was related to a single motion or all .. you basically confirmed it was all .. if you look at the output that you provided in your original post you will see that the errors started when accessing the opensha.usc.edu website .. a wget with the same URL returns a similar error message .. so either the web service that was provided is no longer functional or the calling sequence has been changed .. issuing the following at a terminal window
wget
http://opensha.usc.org:8080/OpenSHA_dev/Site_Data/Wills2015or even placing the url in the browser both return null data.
will look into it further to see if they have moved stuff around.
