We have done this before and I did this again today. At the moment there 
are no biblionumbers existing in table "deletedbiblio" that also exist 
in table "biblio". Menu "About Koha > System information" does not show 
errors anymore.

I have checked the currentauto_increment values for all tables, the 
values in the normal tables are always higher than the ones in the 
respective deleted tables:

  147200 - biblio
  146933 - deletedbiblio

  147200 - biblio_metadata
  68588 - deletedbiblio_metadata

  147200 - biblioitems
  NULL - deletedbiblioitems

  73229 - items
  NULL - deleteditems

So if I understand right with this setup when using MariaDB 10.5.15 the 
problem should no more happen.

Unfortunately I'm quite sure it will happen again anyway (as before). I 
will then write to the list again.

Best wishes: Michael
