Hi there,
It takes time to find the camera that mirror lockup works correctly.
If we have simple commands and procedures to investigate, I think many people will try it.
I will try a new build tonight.
Thank you.

Hello, knro.
Thank you for your information.
I understood that mirror lockup Enable/Disable is not working properly.
The operation seems to be different in some camera models.
Is there a way to disable mirror lockup?
I am worried that the camera will be damaged, as errors will show on the camera side.

Hello.
I have a problem.

I am using Canon T7i (X9i).
The INDI module I am using is indi-gphoto (2.2 to 201807161307 ~ ubuntu 16.04.1).
Although 1 second capture works, can not capture longer than that (eg 2 seconds).
If the capture operation fails, all subsequent capture commands will not be accepted and capture will be impossible.
Sometimes Err 70 is displayed on the camera.
I will attach a log.
When using Canon EOS 600D, there seems to be no trouble.

Are there any advice?
Thank you.

Hi smhxx,

I tried your advice. It worked very well!
A memory leak has not occurred.
The problem is solved with the latest nightly builds.
I checked my environment.
Cause my nightly builds automatic download script seemed to be failing.
I'm sorry.
Also, as you say, note that this problem occurs on the current stable version.

Thank you.

Hi smhxx,
I feel the same way. I am in trouble in exactly the same situation.
If you can reproduce the problem, can you post a log?
It will surely help you to analyze the situation.

The normal log is as follows.

INFO    1001.632236 sec    : Exposure done, downloading image...

The error log is as follows.
INFO    1052.571810 sec    : Exposure done, downloading image...
ERROR    1057.966632 sec    : Cannot convert /tmp/indi_V62GLb : Unsufficient memory
ERROR    1057.967516 sec    : Exposure failed to parse raw image.

An error is output by the read_libraw () function defined in indi-gphoto / gphoto_readimage.cpp.
Looking at the source code, the result of Libraw 's raw2image () is an error.
It is considered an error due to memory shortage, so I do not know whether there is a problem with libraw or indi_gphoto.
There is a possibility that indi_gphoto forgot to release memory.

I tracked memory usage. (ps aux command)
It is a comparison of VSZ and RSS when I capture 10 times.
Count	%MEM	VSZ	RSS	COMMAND
1	10.2	150068	96820	indi_canon_ccd
2	13.7	183432	129996	indi_canon_ccd

10	41.6	448560	395124	indi_canon_ccd

The memory used is increasing about 33000 kb each time it is taken.
And that memory is not freed when the capture is over.
The only way to free it is to restart the INDI server.

Dear Herrhausen.

Thanks for your advice.
Both "Single Window Open" and "Single Preview Tab" have been checked in my setting options.
It seems that this is not the cause, as the INDI server and the KStars client are running on separate machines.

Hello.

I have a problem.
I was capturing using canon T7i.
I download the captured image to the client in FITS format.
After 15 consecutive captures, KStars output the following error.

Cannot convert /tmp/indi_V62GLb : Unsufficient memory
Exposure failed to parse raw image.

And capture was aborted.

When I monitor the memory consumption of the INDI server, many free memory decreases per capture.
When an error is output, the free memory of the server is almost empty.
Also, memory is not freed until the INDI server is restarted.
In order to resolve this error, it was necessary to stop the INDI server and restart it.
There were no such errors in the past.

Do you have good advice?
Thank you.


I am using the following. and Log.

INDI server
Raspberry Pi 3
Ubuntu Mate 16.04
INDI Latest nightiy builds
libgphoto2 2.5.18

Client
Ubuntu 18.04
KStars Latest nightiy builds

Hello.
I have a same problem.
I am using MoonLite Focuser (compatible).
Camera is Canon DSLR, filter wheel is not used.
KStars is 2.9.4, INDI is 1.7.0.
KStars freezes in the middle of autofocus.
It seems to happen after several autofocus data points are gathered.
Because KStars crashed, log could not be obtained.
I try to get the log again tonight.

Hello.
Can I set the exposure time in PAA refresh phase to 1 second or less?
I am using the V4L2 camera for the guide.
The exposure time of this camera can not be longer than 0.5 seconds.
In order to use with PAA, it is necessary to set the exposure time to 0.5 seconds or less in the refresh phase.
Is there any way?

I thank the development team.
Align module does not work properly after becoming a new Kstars.
I am using Celestron AVX.
After moving to the target object, align it.
Executing Slew to Target resulted in "Sync Filed" and alignment failed.
After that all Sync repeatedly failed.
Looking at the log, the command to AVX seems to be timed out.
I am connected with AVX via serial port, and can be controlled normally with KStar.
Please tell me how I can avoid the error.

Hi.

I installed INDI on a new PC, but I get an error.
Distribution is Ubuntu 17.10 & kernel 4.13.0.
