Map tiles not loading

[december1990]

I imported GB data about 2 years ago and immediately after running container tiles were available but I had to add Ireland data, so I stopped containers, and removed volumes and imported Britain and Ireland.pbf and created new volumes, after running container I see nothing and cpu is used completely by rendered in a way that makes server not responding!! has anything changed or I'm doing something wrong ??

I first create volumes for osm-data and osm-tiles then run the following commands

docker run -e UPDATES=enabled -v /home/renderaccount/data/britain-and-ireland-latest.osm.pbf:/data/region.osm.pbf -v /home/renderaccount/data/britain-and-ireland.poly:/data/region.poly -v osm-data:/data/database/ -v osm-tiles:/data/tiles/ overv/openstreetmap-tile-server import

docker run -d --restart unless-stopped -p 8080:80 -e REPLICATION_URL=https://planet.openstreetmap.org/replication/minute/ -e MAX_INTERVAL_SECONDS=60 -e ALLOW_CORS=enabled -e THREADS=100000 -e "OSM2PGSQL_EXTRA_ARGS=-C 10240" -e UPDATES=enabled -v osm-data:/data/database/ -v osm-tiles:/data/tiles/ -d overv/openstreetmap-tile-server run

as far as I know for importing GB I'd used the same commands. I also check the tiles volume but there ano no files, folders there except for planet-import-complete. I remmber there used to be folders 0,1,...20.

I checked the logs for the containe and see the following errors:

** (process:138): ERROR **: 06:13:13.377: An error occurred while loading the map layer 'default': Postgis Plugin: could not look up local user ID 1000: Too many open files

Your problem is likely here:

-e THREADS=100000 -e "OSM2PGSQL_EXTRA_ARGS=-C 10240"

I somehow doubt that your system has (3 + (1 + 100,000) * 14) * 128 MB + 10,240 MB = 179,212,035 MB = 171 TB of memory.
