Hello Marc-Alexandre,
Something gone really weird.
It is probably not a run out of disk, because Virtuoso usually detect such
things properly.
OTOH single 1.1TB file without striping is what I've never tried so I can't say "it
works for me".
Striping to multiple disks is always Good Thing if a database is larger than a
half of RAM.
I've inspected the code, but found no evident reason that may make this
specific size important.
So I'll ask others.

Bottom line, going to a DBMS of this magnitude without stripping
introduces problems at too many levels esp. the host OS limits for
resources such as single files.
This DBMS really needs to have been stripped as outlined above.

Hello,
I've load a complete version of PDB in N3 with an approximate size of
14 billions triples. It completed successfully, but it crash at the
end of a checkpoint and don't want to restart. I'm getting the
following error:
GPF: disk.c:2046 looking for a dp allocation bit that is out of range
Segmentation fault
Also, the first message I've receive, but it is not giving it to me anymore was
GPF: disk.c:1867 cannot write buffer to 0 page.
What does this mean? Is it because of the size of the virtuoso.db
which is 1.1 TB?
Thanks for the help,
Marc-Alexandre Nolin
