HAP ac3 and 15 device of Dude.

After upgrating ROS from 7.6 to 7.11.2 and installing dude + enabling SNMP, RAM began to decrease day by day.
Before this installation, the uptime was 340 days and everything worked perfectly.
I'm not sure, maybe I shouldn't worry and is this normal work after dude installation?

I also uninstall the dude on 7.11.2 and seems everything is working fine.
