I'm unable to upload PDF files to skuid page in IE11 browser at times

The upload is happening good for all the pdf’s in mozilla and chrome but when I’m trying to add few pdf’s, it is throwing an error “Could not upload some particular files” in IE11.
Any help is much appreciated. Thanks in advance

A few questions. 

1. How is this page being accessed?  What does your VF wrapper code look like.  are you using the Skuid:Page component method? 

2. Can you try with a series of PDFs that are increasing in size?  And let us know if there is a break point at which it stops working?
