when removing net for agent dnsmask constantly tries to restart

[Sahid Orentino]

When removing network for agent, dnsmask constantly tries to revive.

This has been observed when using multisegment. The external process monitor is not well unregistered for that service.

This is because the correct helper to get the process identifier is not used for unregister.
