File Upload Error

KNIME Server
#1

Hi,

I have a scheduled workflow, which runs on a daily basis, and seems to work roughly about half the time.

The other time, it has the following error message:

Upload 0:945 - ERROR: Execute failed: com.jcraft.jsch.JSchException: timeout in waiting for rekeying process.

This refers to the File Handling -> Remote -> Upload node, which in this case works off a SSH Connection.

Anybody have any ideas? The most confusing aspect really is the sporadic successes and failures.

Hi,

can you provide us with the executor logs s.t. we can see the full error stack?
What timeout did you set in the SSH connection? Does it help to increase it in case the connection might be too slow to the SSH server?

Cheers,
Moritz
