I was wondering if #17526 (comment) caused this, but if this has been happening for at least a year, then I am unsure.

This test looks familiar, may have a look.

Edit, yes it’s code from 6fa72ceb802.

I was able to reproduce https://api.cirrus-ci.com/v1/task/4686259315539968/logs/ci.log locally yesterday after ~200 runs. I then ran wallet_basic.py overnight with #23136 and no further failures.
