Have you checked the configured mysql heap table size? Have a look at this:

mysql> show variables like "%heap%";
+---------------------+----------+
| Variable_name       | Value    |
+---------------------+----------+
| max_heap_table_size | 16777216 |
+---------------------+----------+
1 row in set (0.02 sec)

The default value is 16MB.
