Drawio keeps crashing about drawio-desktop

zip the file and attach it.

Thank you David. Please find attached the file in question (I have removed some of the most recent generations at the top for privacy / security)

OK, that probably is the largest draw.io file I've seen in 14 years, I feel you deserve some kind of award for creating a 220k line file.

We'll take a look.

You could disable extras->automatic backup and set the draft interval to 0 to disable, but would then need to very cafeful to save often.

And untick extras->autosave

I already have autosave unticked, and have previously tried disabling automatic backup in the past, but without success. I haven't set the draft interval to 0 though. So I'll try that too. BTW, I have learnt to manually save after adding each pair of boxes (for another generation of parents).
Incidentally, adding boxes uses up far more RAM that editing the contents of a box, presumably because all the newly shuffled box positions use a lot of memory, compared to a few keystrokes for a name change.

Hi David,
I did all three (unticked autosave, disabled automatic backup and set draft interval to 0). It still crashed around the 6 to 8 GB mark, but when I killed the task in Windows Task Manager and restarted Drawio, thankfully it didn't try and load a backup.

What about spliting sections into multiple pages and linking nodes into other pages? The problem here is the sheer volume of revalidation and drawing when one thing changes.

I did consider splitting into multiple files, but I have to keep searching on names to check for repeats of parts of the family tree, where two or more children appear, but have the same parents. If the parents' family trees are already done, I don't want to do them again (especially since editing is so slow - to create a new box takes around 20 seconds, and a similar time to change the name in it).
I now see that a search will do so over multiple pages of the same file.
Ultimately it will be printed on one long sheet, so can the multiple pages be rejoined into one page when I have finished?
