> I have an XForms page that periodically refreshes its model instance by
> posting a submission. Ordinarily this seems to work ok and the page gets
> updated as required. However if I leave the page refreshing, from time to
> time I get an Orbeon error dialog with the title "Read timed out" and the
> following information:
>
> Resource URL    Line    Column  Description     XML Element
> oxf:/ops/xforms/xforms-server.xpl       42      58      reading processor output name ?
> dataid ? request-body   <p:output name="data" id="request-body"/>
> oxf:/ops/xforms/xforms-server.xpl       49      60      reading processor output name ?
> dataid ? xforms-request         <p:output name="data" id="xforms-request"/>

> responseid ? xforms-response    <p:output name="response"
> id="xforms-response"/>

> I also get a stack trace in the OPS log file which is shown at the end of
> the message.

> Clearly there is a time out occurring in the system, but I don't understand

> Anecdotally the problem seems worse when using Internet Explorer as the
> browser rather than Firefox or Chrome, which made me wonder if this is a
> client-side issue. Again, if so is there any way to make the system deal
