Another saveImage is in progress so the new one was aborted.

[ukpaudel]

Hi, I have the master branch running on a Raspberry Pi 3 and ZWO 224mc. For a brief moment I had the camera and pi running and displaying images on allsky.local page. Now it no longer works. On the liveview page it says Allsky is running but never displays any images. When I look at the log using 'tail -f /var/log/allsky.log', I get the following error. It looks like it is not able to upload the image. I checked my wifi upload and download speed on Raspberry Pi and it looked pretty good ~8Mbit/s. I have 10sec exposure for nighttime with images updating every 30 seconds.

This is the third time I am doing fresh reinstall, I am completely lost. Any help is appreciated.

Please do the following so we can gather more info to hopefully figure out what is going on:

cd
ps -ef > ps.txt
sudo systemctl stop allsky
# change the Debug Level in the WebUI to 3
# but UNcheck the "restart Allsky" box so Allsky does NOT restart.
sudo truncate -s 0 /var/log/allsky.log 

Then reboot. Once you notice the problem again, attach /var/log/allsky.log and ~/ps.txt.

Hi, thanks for getting back to me. I ended up reinstalling the package again (with a clean start) and somehow it magically works! I worry though I might run into the same problem in the future as I tweak around with the settings. I will activate the post if the problem comes back around.

Rebooting and/or reinstalling rarely gets rid of the underlying problem. It may mask it for a while, but if there's a bug it'll likely reappear.

When users are willing, I prefer to find out what's going on and fix it when possible.
There's a bug somewhere because the "Usage" message from ps in the log file should never appear.

If the problem reappears, please run the commands I mentioned in my prior post.
