IE11 Aborting Http POST requests with network error 0x2ee2

I have posted this same issue on stackoverflow with no response:

http://stackoverflow.com/questions/36631874/ie-aborting-http-post-requests-with-error-0x2ee2

We have tried reproducing this issue but it only happens on a few machines.

Basically, when trying to upload files using either angular $http or jquery ajax, some of the upload requests seem to randomly get aborted, and I get this error:

XMLHttpRequest: Network Error 0x2ee2, Could not complete the operation due to error 00002ee2.

I dont really see anything in the winInet logs.
