Kong crashes on start (MDB_CORRUPTED)

Q: I receive the following error when starting Kong:

2022/04/11 12:01:07 [crit] 32790#0: *7 [lua] init.lua:648: init_worker(): worker initialization error: failed to create and open LMDB database: MDB_CORRUPTED: Located page was wrong type; this node must be restarted, context: init_worker_by_lua*

A: Your local configuration cache is corrupt. Remove your LMDB cache (located at <prefix>/dbless.lmdb, which is located at /usr/local/kong/dbless.lmdb by default) and restart Kong Gateway. This forces the Kong Gateway node to reload the configuration from the control plane because the corrupted cache was deleted.
