Hello, I'm trying to load SF100 data into MonetDB but it crashed. My server: 64bit openSUSE 11.3 mem: 47GB swap: 1GB disk: 1.2T monetDB: 11.15.3 I use DBgen to generate my data. when I'm in a client I execute a script, after a few minutes, the monetDB was crashed. get some error msg like this: HEAPextend failed to extend to XXX for XXXX my script file : COPY records into from nation.tbl using ...; COPY records into from region.tbl using ...; COPY records into from customer.tbl using ...; COPY records into from part.tbl using ...; COPY records into from ...; COPY records into from ...; COPY records into from ...; Does anybody know what's reason for this error ? and how can i overcome this error? Any help would be most welcome:) Thx, keliang
