Hi I've just downloaded a new version of MonetDB a few days ago and started testing it.. I tried inserting a 2.6G data file (12 columns, 32 million rows) and it works fine. But when I added 4 more columns of data to that data file (of type bigint, bringing the file size up to 3.9G), it fails saying !SQLException:importTable:failed to import table !ERROR: GDKload: cannot mmap(): name=20/2023, ext=tail.priv !OS: Cannot allocate memory !ERROR: GDKload failed: name=20/2023, ext=tail.priv I tried searching for similar problem, but only found it for older versions of MonetDB. Is this still an issue in the current version? Thank you. -- View this message in context: http://www.nabble.com/Can-not-allocate-memory%2C-MonetDB5-tp16019364p1601936...
