Error in the executor logs

I am reviewing the Logs of a Linux server in which some flows fail randomly and the recurring error I find is the following one

2022-01-08 18:15:51,580 : ERROR : main : : ProfileManager : : : Could not download profiles from http://localhost:8080/knime/rest/v4/profiles/contents: Archive is not a ZIP archive. Will use existing but potentially outdated profiles.

I don’t know what generates it, if someone can help me, thank you very much.

Hi @lizardovanegas ,

This issue could be because Tomcat is being overloaded and the server is not able to process all of the connections/messages in a timely manner. Could you let us know what your memory settings are for Tomcat? You should be able to find this by editing the knime-server.service and seeing what the Xmx setting is, or if you haven’t set up services, you can run a “ps -ef | grep knime” and see the settings in the output for the tomcat process.

Thanks,
Zack
