Sporadic issues with S3 minutely replica download fails (pyosmium)

[flohoff]

Hi,
i am running osm pipelines every 30 minutes for different tasks and i update pbfs with /usr/bin/pyosmium-up-to-date from Debian Bookworm.

Since the S3 transition i have failed pipelines about 1-2 times a week.

I fetches replication minutelys - something 20-30 and then suddenly one of them fails. This machine does not have a firewall and is directly connected with a public IP. So i doubt its a client side issue with dropping a tcp/http session. I can also rule out DNS issues as one can see its valid resolvable and previous downloads work.

I am not saying AWS/OSMops is at fault. It might be that sporadic issues on AWS/S3 must be accounted for and pyosmium needs fixing.

You need to upgrade your pyosmium - osmcode/pyosmium#237
