(I think that) I found the thread: [Astro binding does not trigger: has no future executions anymore](https://community.openhab.org/t/astro-binding-does-not-trigger-has-no-future-executions-anymore/30403)

Trying to find the PR that fixed the issue… this is old though. @rkrisi is on OH 2.4.0 M6… this shouldn’t happen

and maybe: [Astro: Queue full Error at Midnight · Issue #3809 · eclipse-archived/smarthome · GitHub](https://github.com/eclipse/smarthome/issues/3809)
