The important part here is “RabbiMQHandler Could not acquire enough core tokens from server, quitting”.
I’d check for
a) is the KNIME Server (KS) running? Because the KNIME Executor (KE) needs to talk to the server to ask for core tokens. If the server isn’t up, then the KE won’t be able to get tokens.
b) if the KS is up, is there already a KE running that might have claimed all the available tokens already? Check for multiple instances of KE.
c) are the KS or KE already configured as services? If so, starting it manually may be redundant, resulting in duplicate services attempting to start (see (b), above).
Thank you very much for your reply
You’re quite welcome. Let me know if you have any additional questions.
