Upload fail multipetimes

Hey did you guys have this sort of problem, i try to upload my file multipetimes and it still fail (7.2GB size)

PROCESSING FAILED
Error during processing. Please try again or contact us if you continue to experience issues.

Thx

5GB is max i think ? Mayby thats why.
Anyway the processing is a bit wonky. If i upload more than one file a time all but the first will fail.
So now i only upload one at a time..
