The error is sporadic. A test case: --tarantool.cfg: slab_alloc_arena = 0.1 pid_file = "box.pid" logger = "tee tarantool.log" work_dir = "." primary_port = 33013 secondary_port = 33014 admin_port = 33015 replication_port = 33016 rows_per_wal = 50000 space[19] = { enabled = 1 index[0] = { type = "HASH" unique = 1 key_field[0] = {fieldno = 0, type = "STR"} } index[1] = { type = "TREE" unique = 0 key_field[0] = {fieldno = 1, type = "NUM"} } } Test: lua for i=1, 10000 do box.space[19]:truncate(); for j=1, 30 do box.insert( 19, j, os.time(), 1 ) end; index = box.space[19].index[1]; count = 0; for k,v in index.next, index, nil do count = count+1; end; if count ~= 30 then print("bug at iteration ", i, ", count is ", count); end; end This may print "bug at iteration 0, count is 0".
