my server is running Windows 7 64bits,24GB RAM, MongoDB2.0.1 with journaling enable.

i use c# driver to insert data into MongoDB, each insert data is about 2MB. After a while, MongoDB consumed all of 24GB memory, then out of memory dialog of Windows pops up, I turned the dialog off(twice), then MongoDb was alive for a while then crashed.

The virtual memory(pagefile size) of Windows is 73595MB, it is managed automatically by Windows

There is no such issue if I turn off journaling function, but I need it to reduce time consuming for repairDatabase
