Has anyone seen this error?   We are using the MultipleFileUpload widget and generally speaking it works well but we have seen this error a number of times and are unsure what is causing it.   Any thoughts?

It ended up being an issue with the ASM module on our F5 load balancer.

Hi Josh ,, it could be cause by the filename or type

I had the user email me the file the are trying to upload.  It's a normal PDF named office notes.pdf.   I also uploaded this file to the widget myself in our non-prod environment and it worked as expected.
