The data's size is about 3 Gigabytes.  21,852,641 triples need to be inserted in total.
My machine is 64-bit and only 8G memory for that.

Thank you for your immediate reply.
Kang.

Dear Kang,
indeed, there is no way to limit the memory use. All columns are memory
mapped files,
which give an upperbound on their size. This is particularly problematic
for 32-bits machines and very large columns.

Don't miss this year's exciting event. There's still time to save $100.
Use priority code J8TL2D2.
