Kernel is not starting or stuck.


We have Stopped Adeptia services to Update the Licenses but after license Activation the Kernel is getting stuck or not started. We also tried Killing the Java instances but that doens't solve the issue.

This issue may arise in other situations as well where you tried to Reboot the services but when you try to start the services again but Kernel is getting terminated intantly or gets stuck.

Please check if below Error is coming in the KernelApplication.log file.
