Timeout error when warming up database after planet import

[iAlex97]

Describe the bug After rank imports and database check, the import process failed when warming up the database. I think this is due to https://github.com/osm-search/Nominatim/pull/3172 which sets a default query timeout of 10 seconds.

To Reproduce Start a planet import and wait for it

Expected behavior The import and warm up process should complete without errors

Desktop / Server (please complete the following information):

• OS & Version: Arch Linux kernel 6.5.4-arch2-1
• Docker Version: 24.0.5
• Nominatim Version: 4.3.0

Additional context I will try another planet import with NOMINATIM_QUERY_TIMEOUT set to 600. If that fails, I will disable it entirely while warming up and re-set it afterwards as this mechanism is a good idea. If everything is works out, I will submit a PR with said fixes.
