https://github.com/paritytech/smoldot/pull/2631 doesn't solve the issue but changes the panic message to include the service that has a bug in it, so if it happens again it would be nice to update this issue.
Just personally encountered this:
panicked at 'block already unpinned for subscribe-best subscription', /home/tomaka/Projets/smoldot/bin/light-base/src/runtime_service.rs:394:25
It's unclear whether it's the same panic as the OP, but I'm going to go with the assumption that yes.
This happened while I connected to Westmint. Presumably this could maybe be reproduced by connecting to a chain. EDIT: can somewhat be reproduced by starting the demo, then only opening a browser tab to Westmint
The subscription code is definitely behaving as intended. There's probably a bug in the runtime service unfortunately.
This newly-added debug_assertion panics: https://github.com/paritytech/smoldot/blob/c537c408c4382eab79d56029bc6c24f6a9ab9f6f/bin/light-base/src/runtime_service.rs#L317
Problem comes from here: https://github.com/paritytech/substrate-lite/blob/ca2bc4a01e1ef52a81595a80c7f064c2ebaf0500/bin/light-base/src/sync_service/parachain.rs#L571-L574 We report blocks in a completely incorrect way.
