Freeze on cold start

[Didier B]

Thanks for reporting, hopefully we get a response soon.

Didier, then it could be that you were suffering another extra problem besides the opencpn error.
Let's try to fix the "jumping boats" issue in opencpn and we will see what happens with your system.

I can reproduce the "jumping boat" issue forcing a signal loss but I can not reproduce the opencpn freeze some of you have reported. Could it be a memory problem when trying to load heavy charts on every jump?

I have used the accessory "task monitor" when in 'freeze' situation (called using the window like button, which escapes the freeze condition) and the RAM usage was around 20 to 30 %, while opencpn used 25%  of the cpu capacity. I assume this means 100% of the core allocated to opencpn, generating the 'freeze" condition ...


*** NEW ***
It just happened (the freeze), and when it unfroze I noted the routes and waypoints had disappeared from the screen.
I used the route manager to erase routes and WP and reloaded them from my Back Up, they only appeared in the manager, but not on screen.
I used the manager to centre screen on a route, the map centered but no displayed no route.
I had to change the OpenCPN connection to the UDP one and restart OpenCPN to see the routes on screen again.
Then I changed back to the Signal K connection, restarted and the routes were correctly displayed ! ? ! ? ! ?
For me that is a first  time I see that !

Do you have influxdb running? It's really useful to see what's been going on, this is satellites in view > 

I'm not aware about influxdb, sure I should get !


That's why 'GPS status' loss in the OpenCPN dashboard maters for me !  

BTW, I had, (in the recent past) used the tick box allowing to log a connection in Signal K, I tried to activate it again ; but I coudn't locate the log file after that. Any suggestion someone ?
