Hi all,
We’re migrating to Knime Business Hub and in the phrase of validating whether all the workflows work as expected (after migrating/adapting).
We have actually a problem with some workflows that permit to visualize and modify an huge amount of data (using Table Editor node).
These workflows worked well on Knime server (with -Xmx48g) but they crash on Hub with the following error message :
upstream connect error or disconnect/reset before headers. reset reason: remote connection failure, transport failure reason: delayed connect error: 111
Nothing found in the executor log. Inspect the workflow from Analytic platforms : all nodes are well executed.
We seeked out for more information with our admin, and found an OOM in the rest-interface logs. But we have our execution context already configured at 60g and when the workflow crashed, the memory usage is pretty low (not really change) ~20g over the limit of ~80g.
Any idea to fix the situation? Many thanks in advanced!
Best regards,
Thanh Thanh
