MaxNoOfConcurrentTransactions Error

[Jeff]

I created a simple function on mysql cluster.

1) step 1, create a table t with only one column.
mysql> desc t;
+-------+---------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------+---------+------+-----+---------+-------+
| a | int(11) | YES | | NULL | |
+-------+---------+------+-----+---------+-------+
1 row in set (0.01 sec)

2. step 2, create a function

mysql> delimiter //
mysql> create function loopfunction() returns VARCHAR(20)
-> begin
->
-> declare l_loop int default 0;
->
-> loop1: loop
->
-> insert into t values (1);
->
-> set l_loop := l_loop + 1;
->
-> IF l_loop >= 10 THEN
-> leave loop1;
-> end if;
->
-> end loop loop1;
->
-> return concat('We looped ',l_loop,' times');
->
-> end
-> //
Query OK, 0 rows affected (0.01 sec)

3) Run the function and got the error below:
mysql> delimiter ;
mysql> select loopfunction();
ERROR 1297 (HY000): Got temporary error 4006 'Connect failure - out of connection objects (increase MaxNoOfConcurrentTransactions)' from ndbcluster

4) My config.ini is:
[root@mysql02 mysql-cluster]# cat config.ini
[NDBD DEFAULT]

DataMemory=200M
IndexMemory=50M

How should I set the MaxNoOfConcurrentTransactions? Thanks!
