Anyone seen anything like this before?

306 active files in an Integration but no master file generated???

Check the log file, your answer will likely be in there.     

This hiccup is not a major one though, you can simply load up the ImageIntegration process, load the files from the registered folder and hit go.

Okay, it was buried in the log file.   Looks like a PixInsight internal error happened here.

No idea how to work around or fix it.

Running Image Integration manually still crashes.

I had to remove one of the subs from the stack to get it to integrate.

Weird.

Hello, from what I see the main issue is revealed in this part of the logs:

[2025-07-31 00:40:08] *** PCL Win32 System Exception: At address 00007FFA56E39F0A with exception code C0000005 :
[2025-07-31 00:40:08] Access violation: invalid memory read operation at address 0000000000000000

That looks like a low-level system error judging by it's exception code "C0000005", which is generally for "Access Violation".

"invalid memory read operation at address 0000000000000000" - Here it seems like Pixinsight tried to read data from memory adress 0 or null. This usually gets triggered by bad or corrupt data.

This does not seem to be a generic memory issue, since your log states you have enough available memory to complete the task.

All of this points me toward a corrupt or "bad" data. 

John Stone:
I had to remove one of the subs from the stack to get it to integrate.

Since you removed that one frame and it integrated, that was the culprit. Either the frame was corrupted during writing to the disk, or simply had bad pixel data.

Even if the frame was not corrupted in any way it can cause this issue if it looks different enough than other frames. It looks like you just ran into an unfortunate bug in the software.


Hope this helps.
Clear Skies, Rene.

I misspoke earlier when I said I had to remove a sub to get it to work.  What I really had to do uncheck the “automatic memory“ checkbox  (just used the default values) 

That enabled the integration to complete.

I think this is a rare bug in PixInsight since all other filters (besides Blue) worked fine.
