[Tile-serving] [openstreetmap/osm2pgsql] Unable to import planet after repeated attempts on powerful machines (#930)

[Max Heinritz]

>So you've got some Memory allocation failure in osm2pgsql before, which is no longer the case with 64GB RAM?

I'm not sure. Based on similar failure modes and the comments the threads linked above, I assumed my previous attempts failed due to some kind memory constraint on the client. When I used a 64GB machine, I ran all the same commands as my earlier attempts except with `--cache 35000`. While the command was running I ran `htop` and saw totally memory usage around 45-50GB, iirc.

>Did you have swap memory configured earlier on?

I am not sure. I just had whatever the default is on ec2 instances. Literally the only commands I ran were those listed in https://github.com/openstreetmap/osm2pgsql/issues/930#issuecomment-490649475, then downloading the planet file from s3, and then the import command in OP.

Hope that helps. Happy to provide any other information and thanks again!
