Re:Unexpected shut down of KStars and Ekos, but not Indi server #44156
I also have that problema, using Stellarmate on a Raspberry pi 3b+.

While guiding and imaging, suddenly Kstars disappears but PHD2 continues guiding and Indi seems to remain connected.
After i restart Kstars and connect, a pop up window tells me that there is already an instance of Indi running. I chose to stop it and then Kstars can start workng again.

Greetings.

Re:Unexpected shut down of KStars and Ekos, but not Indi server #44170
Looks to me this is a Raspberry Pi problem. It does not happen (or only very rarely) when I am running KStars on my Zotac mini-PC.
May be it running out of memory. I added 4 GB swap and that seems to have helped.

Re:Unexpected shut down of KStars and Ekos, but not Indi server #44173
Yeah, If it happens on Raspberry PI and not on another computer, it probably is a memory issue. But if you can reliably produce a crash on different systems, we should see why it does crash.

NOTE: I wouldn't recommend a SWAP file on a raspberry pi due to issues with reading and writing of the SD card. You will wear it out. There is something much better called zram. Basically it takes the system ram, makes a compressed swap file for it, and puts the swap file in RAM instead of on the system disk. There is a slight performance hit since the system now has to do access compressed ram on a swap file in memory instead of just accessing memory. But the performance hit is worth the system not crashing. And it is also better than wearing out your SD card.

Re:Unexpected shut down of KStars and Ekos, but not Indi server #44174
Hi Rob,

I can't "reliably" induce a crash of KStars, it seems to happen randomly to me, at least. The Zotac mini-PC I am using also has just 4 GB of RAM, but my Swap file there resides on the eMMC, not an SD card.
With respect to wearing out the SD card, I am less concerned about that. First, I had a swap file on my Pi3 and that was used extensively over the last year without any problem. The Swap file on the Pi4 so far appears to be used very sparingly (swappiness set at 20) and I put it only as a safeguard in case memory gets tight. Second, I don't know how to turn on zRAM in Ubuntu MATE on the Pi4. What is the procedure to do that? Third, microSD cards are really cheap now (I am using a 128 GB card from Samsung that costs $20 and it already last for over a year).
I actually ran my Pi4 without a hitch through the night 2 nights ago, but I did not use guiding. I have the suspicion that handing two cameras and other intensive tasks might be the problem. One of the crashes I had earlier occurred right during the meridian flip.

Re:Unexpected shut down of KStars and Ekos, but not Indi server #44177
For Ubuntu MATE:

sudo apt -y install zram-config

It takes care of everything. If you currently have 4 GB of ram, this will give you close to 8 GB

Re:Unexpected shut down of KStars and Ekos, but not Indi server #44178
Last night I tried my first session with my RP4 2gb running KStars on Raspbian.
Polar alignment ran perfectly and smooth (also in full screen).
Guiding ran so I started a small imaging session of 1x60s, 1x120, 1x180, 1x240 and 1x300s subs. During the 180 sub, I wanted to check the Stars on the 120 s and my messing about with the fits viewer, while guiding and taking a 180s sub, caused KStars to crash.
After restarting and reconnecting etc I tried the same imaging session again, this time leasing the poor fits viewer alone. This time no crash.
I then slewed to a New target, solved and synced and started a one hour session of 30s subs - no problems. Darks, Bias and flats afterwards without problems.
So I’ll just try not to push my 2GB RP4 too hard :-) I did notice that my cooler fan was running pretty much all the way through my session.

Re:Unexpected shut down of KStars and Ekos, but not Indi server #44179
Just wanted to inform that i have crashes here too. Running KStars on my ASUS VIVOBOOK with KDE Neon and Plasma.
I can sometimes trigger that by using the fitsviewer, and sometimes its just out of nothing...
But when a session is running, and i do not do too much clicking around its stable.

cheers

Same here. I don't remember crashing in another module, but most of the time if I play with the fits viewer, trying to zoom or touching the "default zoom" or anything related I crash 8 times out of 10. Very frustrating, so I try to do without using the zoom feature at all.

There was a fix to a crash in FITS Viewer in nightly builds a few days ago. So it would help to know if you're using nightly or stable. For the advanced users, a gdb backtrace would *immensely* helpful.

Re:Unexpected shut down of KStars and Ekos, but not Indi server #44408
Last night I had a successful session with my usual setup having switched back to my Canon 450D. At first I tried my 550D, but on each of two times I tried to Polar Align, KStars/Ekos would crash just before showing the Alignment Frame I.e. at the end of the 3 plate solves. Back with the 450D and no crashes. I noted a significant difference in the solving times between the two cameras 9 secs for the 12Mpixel 450D, twice as long for the 18Mpixel 550D. Next clear night I’ll try out my RPi4 4GB rather than my 2GB, although the latter is housed in a flirc case and stays very cool outside with no fan.

Re:Unexpected shut down of KStars and Ekos, but not Indi server #44422
does the software updater on the pi4 os check for the nightly builds ?? if not, how do you set the pi4 updater to check the nightly builds ?
