[MonetDB-users] monetdb crashed when using copy into .... locked

Hi: does anybody know what's the problem with the copy into of locked? we want to use concurrent copy into to a table, seems montdb not good at this. some body says add locked, we try, but the database crached. we just test like this copy 200 OFFSET 1 RECORDS into f_activity from 'd:\bcp.txt' USING DELIMITERS '|','\n' NULL AS '' LOCKED seems need single user mode, but how to set single user mode?
