Hi John,

it could just be that the client connection timed out?    Could their network have failed part way through an upload?

regards

I'm using Jetty 9.4.30. Yesterday I saw the following error:

org.eclipse.jetty.io.RuntimeIOException: java.io.IOException:

I googled this, and found that this has been reported for users of the
Apache fileupload package. Although I am using that package in other
servlets elsewhere, this did not happen in a multipart request -- it was
a normal post request submitted by a _javascript_ XHR at 60 second
intervals to track changes to a form.

About 20 other users were doing the same thing at the same time, but it
only happened for one of them. It happened once, then there was a 7
minute gap, then four successive requests failed at 60 second intervals,
then it worked as normal from then onwards.

I have now rewritten the fileupload code to use getParts() instead, just
in case.

Any ideas what might have happened here?
