A note has been added to the 6.0.8 changelog: When performing an online DROP INDEX on a Falcon table, the operation may conflict with other index operations such as including index scans. When one client drops an index, another client may initiate a concurrent index operation that accesses the mapping object of the index being dropped, and this can cause a crash
