Issue/Introduction

Starting to having problems with APM. 

The Introscope Workstation console is not responding.

We have tried to stop and start MOM, using 

sudo -u instroscp /etc/init.d/introscope10 stop and it didn't stop the service.EMCtrol.sh

Finally, we killed it and ran sudo -u instroscp /etc/init.d/introscope10 start and it didn't start.

Restarted the machine. MOM EM came up and Workstation connected , but the Agents do not expand. 

 

Environment

Release : APM 10.7 SP3

Component :Introscope , Workstation

And also clear the Introscope OSGI Cache on all EMs before restart them
