This error message can be cause by
a) An aborted input stream. For example, the client browsers user may have
pressed "Stop" or
switched to another URL. In your case, it might also occur that the load
balancer switched
the cluster machine. (Which would, of course, be an error in the cluster,
so that's unlikely.)
b) An error in the multipart/form-data parser of commons-fileupload. This is
also unlikely.
Nevertheless, it is possible. However, for obvious reasons, this cannot be
analyzed
without you providing an example of the data causing the problem. For
example, you might
use Wireshark or a similar tool to catch network traffic. Or, if possible,
extend your logging
to trace the clients input stream.

This is a question, which is completely unrelated to the commons-fileupload
library. Ask your clusters vendor or whoever might know the cluster.
I'll wait for some weeks, whether you are able to provide more data. If not,
I'll intend to close this bug as "Invalid".
