User specified the parameter db_nk_cache_size (where n is one of 2,4,8,16,32), while the standard block size for this database is equal to n Kbytes. This is illegal.
Specify the standard block size cache using db_cache_size (DEFAULT pool) (and db_recycle_cache_size, db_keep_cache_size if additional buffer pools are required). Do NOT use the corresponding db_nk_cache_size parameter for the standard block size.
