hi, i'm using monetdblite-r 0.5.0 on a confidential dataset. my syntax worked on monetdblite 0.3.1 on the same machine ftruncate: Invalid argument Error in .local(conn, statement, ...) : Unable to execute statement 'CREATE TABLE ccaed123_b_svcmon_xwalk AS ( SELECT a.enrolid , a.yr , a.dataty...'. Server says 'MALException:algebra.join:GDK reported error. !ERROR: GDKextendf: c !ERROR: HEAPextend: failed to extend to 2890530816 for 02\57\25766.tail: GDKmre map() failed '. it's a local drive, the hard disk isn't close to full and the machine has 700gb of ram, but the table it's trying to create might be bigger than that. dunno if related to https://www.monetdb.org/bugzilla/show_bug.cgi?id=3791 thanks
