Karaf Shell Error

Mahboob · ‎2019-04-04

Has anyone faced an issue where the Karaf dies and comes back up after a good few minutes (like 10 min or more). When this error occurs I am kicked out of Karaf client and can't log back in during interim (get the following error --> "Failed to get the session."). This happens if I deploy/undeploy or update the .cfg file etc consistently. I am pasting the log, which highlights the error (not sure how helpful it will be) !!

Thanks,

Mahboob

Hello @mr

Could you please give us a more bit description to repro your issue? On which talend esb build version you got that?

Please have a look at this jira issue:https://jira.talendforge.org/browse/TESB-21576 to see if it is what you are looking for?

Best regards

Sabrina
