Any chance you had or have long-running transactions. We once had
very low free space in a big database which suddenly ballooned. It
turned out an application programmer had left a connection in "idle
in transaction" state for a few days.
Another possibility is that you had an update or delete which
affected a lot of rows. Even if it rolls back, it can cause bloat.
