History strange behaviour

Hello! After X days i lost 3/4 entities in history (total 10 entities)…
i have to to restart HA and history comes normal.
I’m using last HA version, only 10 entities in history and recorder.

This is my recorder.yaml configuration…

  purge_keep_days: 30
  auto_purge: true
  commit_interval: 30

Someone with a similar problem???

thanks a lot
