RPI high CPU load...
Yesterday when sailing, opencpn became really sluggish to a point where it locked up when activating a route.
Restarted the Pi and checked the CPU load....
What I noticed is an application name "NODE" was running at 104% CPU usage...
When I killed it, my data feed in OCPN (from Signal K) disappeared. A few seconds later the data re-appeared and when checking the list with applications, the application "node" had returned as well. (under a different PID)
Is this the Signal K application?
BTW, running a RPI 3B+

Yes, Signal k server is a nodejs application.

check your signal k settings
