I am getting this error during my graph run. I am reading 14 large csv files and trying to consolidate into a single file.

Here is error log of message:

Hello,
the error occurs, when CloverETL tries to save data flowing through the phase edge (for more information see topic Clover graph and temp space). If you don’t really need, you should rather not use the phase edge.
Please check if you don’t have files like .fbufclv* in your temp directory after graph execution. If they exist, delete them.
You can change the temp directory by running the jvm with -Djava.io.tmpdir=<path_to_requested_temp_dir> option.
