Broken pipe normally occurs when the browser drops the connection (e.g. if you quit your browser while downloading a dataset you might see this). Can you describe in more detail how the "frequent hiccups" manifest? -- James Taylor, Assistant Professor, Biology/CS, Emory University On Mon, Mar 4, 2013 at 12:36 PM, Thomas van Gurp <thomasvangurp@gmail.com> wrote:

Dear all,

Any idea why this might be an what I would need to check?
