Now, the top DB errors on the production is Wikibase term store: https://logstash.wikimedia.org/goto/fc2df3f12166030c02ec92bba71d7924
It's full of things like:
```
Duplicate entry '\xE8\xAA\x9E\xE8\xA8\x80\xE7\x9A\x84\xE9\x9F\xB3\xE9\x9F\xBB\xE5' for key 'wbt_text_text' (10.64.48.26) INSERT INTO `wbt_text` (wbx_text) VALUES ('語言的音韻包括這種聲音')
Duplicate entry 'lingua di scrittura' for key 'wbt_text_text' (10.64.48.26)
Duplicate entry '178959-be-tarask' for key 'wbt_text_in_lang_text_id_text_id' (10.64.48.26)
Duplicate entry '246301-ml' for key 'wbt_text_in_lang_text_id_text_id' (10.64.48.26)
```
(it happened 20 times in the last four hours)
How to reproduce:
- update some terms of a sandbox property (e.g. https://www.wikidata.org/wiki/Property:P370) , in different languages at once (two languages, one term each should be enough), making sure that the new values are uniquely new in the database.
What to expect as a fix:
- errors do not show up on right after updating terms from termbox https://logstash.wikimedia.org/goto/fc2df3f12166030c02ec92bba71d7924
