************************************
************************************
Introscope Enterprise Manager failed to start because:
An error occurred while loading the Management Modules.

We checked the modules directory permissions, and there is not any issue. If we move the .jar files from <EM-HOME>/config/modules directory, the EM starts without any problem.

Environment

Release : 10.7.0

Component : APM EM

Resolution

It seems like ADA-APM_ManagementModule.jar is causing this issue.

ADA-APM_ManagementModule.jar, this management module seems like belong to ADAExtensionForAPM component.

This environment is not using ADAExtensionForAPM component, thus removed the ADA-APM_ManagementModule.jar from <EM-HOME>/config/modules directory
