MM5 crashes while autotagging and switching to main screen

[aboelen]

L.S.,

When auto-tagging a bunch of files and then switching back to the MM5 main screen to check on other tracks, the program crashes.
I select a set of (approx 20) tracks and select auto-tag in the menu. Tagging starts as expected. Then I want to go back to the main screen while auto-tagging is ongoing. I open - in this case - artist view and try to scroll down, MM5 becomes unresponsive (I have now approx 2000 artists in the list so a little lag is not uncommon) and after a while an error message pops up. In this case with log ID 8D508E15. When I go back to the auto-tag window the content is unresponsive, although I can manage window size etc. Then I have to restart MM5.
This error repeats every several auto-tag actions; I have no exact count. Might be the number of files tagged or the number of auto-tagging actions though. I will keep count next time .

When I try to restart the program another error pops up this time with log nr 5C630000. These two might be related. Both the MM5 main screen and the auto-tagging window are white and unresponsive. I then can only kill the program using process explorer.

AJB

Another crash when autotagging (crashlog ID 307D71DF)

I was auto-tagging one directory, then heading back to the mainscreen, autotagged a few more files while the first auto-tag was still in progress. Then, when doing a file reorder based on tags, the original tagging window came to the front flashing with the background of the renaming window. MM5 became unresponsive including no respons on the restartbutton in the error-window. After trying to restart another errorlog (5C630000) was generated. flashing continued but now with a white screen (icon flashes orange white screen flashes between grey edges and full white). Then I killed MM5.

Thanks for reporting.

Should be fixed in upcoming builds.
Let us know your test results with the new build (once is available).

Also with version 5.0.0.2255 MM5 crashes when auto-tagging and then perform other tasks in MM. In this case renaming files based on their tags (not in any way related to the files being auto-tagged). Crashes do not occur always but after having been auto-tagging a range of files. I tried to keep a count but have no exact number. It was between 30 and 50 auto-tags in 4 different runs.
With the crash the auto-tag window and the rename window seem to battle for being the frontmost window. They both lose... that is, they become both unresponsive and I have to kill MM5 with process explorer. The restart button on the error handling window produces error ID 5C630000 and two alternating white windows...

The error window indicated the error-ID would be copied to memory... this is what Ctrl-V reproduces (obviously not only the code itself):

Hi,
Unfortunately LOG file do not show much.
I tried to replicate the bug yesterday for 2h without success, at one moment I had 10 Auto-Tag queue.

Can you please let me know if you have multiple auto-Tag windows open?

We need any specific steps in order to add additional debug messages and cath more precise point of crash occurrences.

[aboelen]

Pavle,

At the moment of the crash I had only one auto-tag window running. I pushed [OK] on the renaming window. Then that window and the auto-tag started to alternate. I had run several other auto-tags before that moment but these where all ready and closed.
I will do a run tomorrow with a Windows debugger open in the background (to provide some extra debug info). I will try to log more accurate, the number of auto-tags done and/or screens open when the error reappears.
The error feels like a buffer overrun. Might it work to enhance the buffer space? Is there a startup parameter I can provide to MM5 that does that? What is the default buffer space or is it assigned dynamically. Perhaps I should lower the buffer space first to see whether the error appears earlier. Then it is more likely that the issue is connected to buferring.

Regards,
Alexander

Hi,
I agree with your assumption. It looks like buffer overrun, and maybe my PC is problematic (AMD 2700x, 64GB RAM, 970 Pro NVMe) so my buffers clean them self more efficiently

Let see if we can catch it this time.

[Lowlander]

I'm not able to reproduce with 2259.

[aboelen]

With the latest version (2264) I reproduced the error.
See the log send with this error code AD94A819.

Again it is only after using using auto-tag for a while. I was moving an album to its new destination. The crash occurred when I selected the artwork files to be moved with the music files. Immediately when I pushed the OK button, the tagging window started alternating with the main window, fighting to be in front. From that moment on both windows where inaccessible (even the closing X or a close window command from the desktopbar did not respond). After a minute or so the error window popped up.

I noticed that the mediamonkey engine stays alive when the program is stopped using the stop button in the error window (mediamonkey.exe is stopped correctly). The engine keeps the - inaccessible - tagging window on the screen. Had to kill it using process explorer.

For as far as I can see it is not a hardware memory shortage (nor RAM, nor drive space) or processing limit. Process explorer indicated that I used overall less then 10% of the available processing capacity and approx 30% of the available RAM when the crash occurred. Also the internet connection was stable at approx 200Mb up and down.

Hope the error log gets you closer to finding the culprit.

best regards
