Uploading a CFF throws CherryPy "No space left on device" errors sometimes

Inez:

I tried to upload the file using just the default settings on the TVB interface for uploading a CFF, which has worked for other CFF files that were generated the same way. I'm getting an error page that looks like what I've attached here. Do you know what the problem could be?

The CFF has all the same attributes as other files and was created using the same pipeline (connectome mapper). Duke, my labmate who generated the file, is checking for any undetected issues on his end as well. I believe this is a file issue rather than anything to do with TVB since I have recently uploaded other CFFs to the latest version of TVB without getting this error. Any insight you have would be greatly appreciated!
