I don't know, I saw that also and did not know what Phonon was. It looks like it is a video/music player app that Kstars uses if you play sound. I don't know whether I can just uninstall it or whether I need to reinstall it and make sure it finds what it needs to work. I am not sure why it is coming into play here, but it is there.

I was thinking the crash might have something to do with the solver running multiple threads and not cleaning up it's 'buffers,' because the way I got it to work again was to limit it to a single thread. It would be nice to have a 'restore' function that when Kstars crashes you can clean up any memory it was using, so a restart would leave the Rpi in a start fresh condition. The server continues to run, the equipment all stays connected, PhD2 is still running in the background, just Kstars, Ekos, the Fits viewer and Indi control panel go away. Restarting Kstars/Ekos is not a problem as all the equipment is still connected, so it only takes a minute to get back running. But if the solver continues to crash it, that is where it really becomes annoying.

thanks for that insight,
Ron
