It appears that the secondary process is attempting to access the database, but the database is locked (possibly by the main process).

Should be fixed by #7932. It is still not clear why another process holds the database lock for a few seconds, but at least now, the current process should not attempt to delete the database file in this situation (which is a possible reason for the I/O error)
