[Dspace-tech] Processing of multipart/form-data request failed. Stream ended unexpectedly

[Andrea Bollini]

Hi all,
we are experience a lot of errors uploading files from a specific
workstation. From this workstation with all the browser available
(firefox, IE, Opera) it is impossible complete an upload.
We always get the following exception:

> Exception:
> java.io.IOException: Processing of multipart/form-data request failed. Stream ended unexpectedly
> at org.dspace.app.webui.util.FileUploadRequest.<init>(FileUploadRequest.java:139)
> at org.dspace.app.webui.servlet.SubmissionController.wrapMultipartRequest(SubmissionController.java:1405)
> at org.dspace.app.webui.servlet.SubmissionController.doDSPost(SubmissionController.java:255)
> at org.dspace.app.webui.servlet.DSpaceServlet.processRequest(DSpaceServlet.java:147)

The error occurs with files of any size, and from other workstations we don't see any problem.
Apparently, we can't check this directly, there is no firewall, proxy or network limit/special configuration between the client and the DSpace server (1.5.2)...

Any idea/previous experience with this issue? do you have any suggestion about test that could help to collect more information?
Thanks,
Andrea

Andrea,

I've never seen this particular error before, to be honest. However, I
do recall seeing similar (usually random) issues when uploading larger
files across an unstable (or bogged down) wireless network.

The "Stream ended unexpectedly" error looks almost like the upload is
timing out (does the browser just hang for a while after uploading?) or
somehow being interrupted. But it's hard to say what could be causing
this -- especially from just a single machine. If it's only happening
from one machine it seems like that machine's network connection could
be having problems (though it sounds like you've already started looking
into that).

Anyone else encounter this with regularity? Or have any ideas?

I have notice that I have missed to share the end of the history...
well, the problem was related to the traffic shaping of the packeteer nothing was wrong in DSpace or in the server configuration.
Hope this could help someone in future,
Andrea
