I was using the CDK connectivity node in order to keep only the largest connected molecular fragment for a large compound database. While running I obtained the following error:
ERROR KNIME-Worker-4 BufferFromFileIteratorVersion20 : Errors while reading row 1298996 from file "knime_container_20140821_6327245083606609536.bin.gz": null; Suppressing further warnings.
Nevertheless the node seemed to successfully finish its task and finally it was tagged with a green status. Do I have to worry about this error? You can find attached the error log.
