Knime 3.4 Errors

Hey everyone,

I was eager to try out the new Knime 3.4. So a few days back I installed it to test if there might be any features making chemoinformatics easier.

Now I have realized that the new Software keeps failing usually with Blob errors.

Either the Node content cannot be displayed or a Loop end fails with such an error. 

The loop failes with:

Execute failed: Error while writing to buffer: Blob file location "/home/XXX/Desktop/col_72/000/000" does not exist

Whereas I get this warning in case the content is not displayed correctly:

WARN  BlobWrapperDataCell             /tmp/knime_structure_curat1389/knime_container_20170719_7772437264436325343/col_0/000/000/-1.bin.gz (No such file or directory)

I am running knime on a 64bit Ubuntu 16.04 LTS with 8GB RAM and Intel® Core™ i5-4670S CPU @ 3.10GHz × 4

These errors force me to reset the whole workflow and start it again, which is painful if there are nodes which have a long running time.

I am using Knime to curate chemical datasets with arount 2000 Molecules as sdf as wells as smiles column, might that be a cause?

Did anyone experience these Issues as well?

It would be great to get some help!

Thank you,




Hi Jennifer,

Can you confirm whether the error occurs for specific nodes, and if so which ones.




thank you for your reply. Sorry I was out on vacation,hence the late reply. I will look into it again, but I remember it for the row splitter node, which wasn't able to load the output at all.

As soon as I am experiencing the issue I will get back to you with more information.
