user7339: I'm getting errors when starting up my producer suggesting I'm out of storage. It looks like db/immutable is the culprit taking almost 100g of space. I'm not super familiar with what this db is or what writes to it.
Is this possibly cardano-db-sync which I'm running by mistake? Is this unneeded for my producer and is it possible to safely delete these files and remove whatever process is writing them?

Yes, that is part of the cardano-node's on disk storage. I have just checked mine (on Linux) and the disk space used is only 72G. Looks like you may have some extra files in there taking up space.

Is this possibly cardano-db-sync which I'm running by mistake?

Very unlikely. Look at the logs. If its db-sync it will very clearly say so. Likewise with the node.
