Activity monitor shows service Down icon

Hi,

I'm currently facing some strange behavior on my Netbackup Env.

On the 7.5.0.4 Master Server (Windows 2008R2 Virtual Machine), there is permanently a Red Arrow Down icon.

But everything is working, no issue, so job failed, no service down...

From my point of vue, if there is some Red Arrow Down icon means that something is not working properly..

Help will be appreciated.
