it usually occurs if an EEM session crashes during a group update.
Thanks for prompt response safeboot.
I believe group update is a automatic process. Could please explain bit more.
When I do force sync to machine from EEM server console it happen from both group.
How can i resole thi issue? Do I need to delete those machine manually?
it's only one machine still, it's just referenced in two different groups. You'd have to delete it from one group, do a cleanupmachinegroup on the other, then restore it.
That would probably resolve the view problem.
Thanks Safeboot and sorry for late reply,
Today I perform said steps and seems it resove the issue.
i don't want to disturbe production server, so first i perfomed this steps for two machine. One machine was working/syncing with server but another one giving error "Object not found" at client side. from server force sync was working fine. So i just restore deleted object and it is working.
Now server and 500 + cients are under monitoring.
