Default Bioanalyzer: What are these huge fragments (after Illumina TruSeq RNA sample prep)?

Hi everybody,

This has been my second time doing a library prep using total RNA from plants. I used the Illumina TruSeq RNA sample prep kit v2.
Last time, everything worked all fine but this time after the final pcr step, the bioanalyzer results all show a huge peak at the beginning of the curve (see attachment).

Can anybody tell me what this is, where it could have come from and what I could do next?

Thanks!!!
