Restsdk-server.toml eating all resources

I have about 10 or12 instances of restsdk-server.toml running on the cloud eating up 80% of CPU and mem…

I killed it obviously but what is it for?
and is there a more permanent solution from preventing it from loading multiple instances

WD updated the firmware… lost adb and ssh …
buggers should’ve given us an option if want to upgrade rather than forcing it upon us

EDIT
I might be mistaken… for some reasone the local ip changed !?
sure i previously reserved it .
