[Monetdb-developers] about copy command of Monetdb

Dear all, Recently,I use TPC-H test the Monetdb, On windows ,so I use "copy ,, records,,,into,,from" to load data to Monetdb,when the size of the file is about 700M,It is OK.But when the size is 1.4G,the Monetdb server is auto stop when loading. But when I am in Linux, it is no problem. So I want to ask why it is wrong on windows when the file is so large? Best regards,
