NINA crashed during night run

[Daniel Lorenzo]

This morning, noticed that NINA had crashed during the night run.

This error occurred after 3am, 31 times in milliseconds intervals, like in a loop, unhandled exception:

The rest of the system was stable and latest captured 5min subs flawless.

Attached the logs.

PS: The level is currently set to INFO. Should I set to a different level for the next runs?

Hmm - Never encountered this issue.

It seems to be a bug in the WPF framework which N.I.N.A. can do nothing about.

[Daniel Lorenzo]

Would it be useful to run at a more verbose log level in the future to better troubleshoot?

I’m runnning NINA on a headless computer, which I access using a Remote Desktop connection. I’m wondering if window/screen resized when closing session or client computer wen to sleep caused some error. I will try to reproduce the problem…

Before i start a ghost hunt, did you make sure that your operating system is up to date as well as your video card drivers?

[Daniel Lorenzo]

I will do that tonight

[Daniel Lorenzo]

No discrete GPU is installed on the machine, and Windows Update did not indicated update for the APU

However, there was an update for .NET framework, and I applied it.

I turned logs to “trace” and will test it out. Will get back with results.

Last night was all right and it survived 24h after that. Closing.. I’ll leave the logs at trace and post an issue if more trouble.

Just to follow up, NINA app was never closed multiple days in a row and imaging multiple nights without crashing.
