Disk Failure when copying 2GB file to store

System

I am trying to copy a 2GB file to my backing store. It gets to the end of the copy and then fails stating "Cannot copy myfile.zip: More data is available.".

I get a "disk failure" in the GUI and have to restart the TeamSite service.

iwtrace.log has the following.
[PHP]

I have been trying to find a solution for this for a few months now. It's not the file since it happens on other files of that size. If I remove some of the contents of the zip to make it smaller it works.

I have over 90GB available for disk space.

Any ideas?
