[GRASS-dev] v.in.ogr Killed by Linux for saturating RAM+SWAP

[Yann Chemin]

Answering to my own question.

I can increase the SWAP size on a running Linux by:

sudo swapoff -a
sudo dd if=/dev/zero of=/swapfile bs=1G count=8
>> 8+0 records in
>> 8+0 records out
>> 8589934592 bytes (8.6 GB, 8.0 GiB) copied, 12.7623 s, 673 MB/s
sudo mkswap /swapfile
>> Setting up swapspace version 1, size = 8 GiB (8589930496 bytes)
>> no label, UUID=xxxxxxxxx
sudo swapon /swapfile
grep SwapTotal /proc/meminfo
>> SwapTotal:       8388604 kB
