Is there any update / response from QHY?

So I analysed /var/log/syslog and found what happened.

The following log entry was written into the log file at a rate of SEVERAL HUNDREDS OF THOUSANDS OF TIMES A SECOND.

kernel: [3314.xxxxxx] usb 4-4: users: process 3751 (indi_qhy_ccd) did not claim interface 0 before use

Using
grep -c "indi_qhy_ccd"
returned 211,661,935 matches in /var/log/syslog.

I think this is a major issue, but I understand that this might be an issue with the QHYCCD SDK, not INDI ...

So I have an update.

Disk space became full again last night. I enabled logging on file though.

I am going to check what actually happened. But for now I think that this happens when the computer fails to download an image from my QHY165C, i.e. it is stuck in "capturing an exposure". This problem occurs rather frequently on Ubuntu 18.04 and macOS with INDI.

I should also mention that a similar problem with my camera exists on Windows (SGP), but instead of being stuck at exposure it is stuck while downloading the image.

Kind regards,
Jonathan

Thanks for the advice. By using the LiveCD I was able to recover one of my systems.

I am going to disable all the logs now as a temporary solution.

Eventually I mitigated the problem by downloading the files manually from data.astrometry.net.

So, just for further reference if anyone encounters the same problem, here is the procedure to download the index files manually.

1. Use a FOV calculator (or ask Ekos to solve an image using ONLINE astrometry.net) to determine your FOV.
2. Once the FOV is determined, the automatic downloader in Ekos will tell you which index files are required and recommended for your setup.
3a. Go to data.astrometry.net/4100/ and data.astrometry.net/4200/ to download the required/recommended files. Make sure these are moved to /usr/share/astrometry (sudo may be required if doing this via command line). OR
3b. Visit www.stellarmate.com/support/ekos/align.html and download all the corresponding.deb files which are associated with the index files desired. After that, install them in one go with the following command

sudo dpkg -i astrometry-data-*.deb
.

Cheers,
Jonathan

Hi,

I am having problems downloading the index files for local astrometry.net plate solving. After the download is complete, an error complaining about the backend of D-Bus (see the screenshot attached) popped up and then the index file remains unchecked (i.e. the file is downloaded but then the error prevented it from being added to KStars).

Any help would be greatly appreciated.

Kind regards,
Jon

The files in which logs piled up were /var/log/syslog and /var/log/kern.log.
I suppose by disabling debugging the logging is off?

Thanks,
Jon

Hi Jasem,

Thanks for your tip. However, it looks like that the CCD logging cannot be enabled in the first place. Am I missing something?

Cheers,
Jonathan
