I can report that MM5 becomes very stable when disabling the aotomatic update of tracks. One can work very quickly. Then, by pressing Ctrl+S, a large number of tracks can be written to the disk with no crashes.

Thanks, the crashes 0EB4CD49 and 0EB4D01A will be fixed in the next build.

Hi,
yes, Select Tracks and just press CTRL+S to save tags to files.

I will try, and give my report. But, what will happen, then? Could I be able later to update the tags "manually"?

If that is the case can you confirm that if you disable immediate update in (Tools -> Options -> Lilbrary -> Tags and playlist) fixes teh problem?

When you update tracks in the data base, MM5 crashes when you start to create a queue of succesive editions, and the list of tasks in process accumulates large number of items (100 or more). It is aleatory, but I am attaching some error log numbers, if that could help.
Maybe the problem is some kind of excessive delay or difficult comunication with my NAS drive (over wifi).
