[CRITICAL] Memory leak with geo

[VolanDeVovan]

Describe the Bug

When I launch Umami, the service consumes all of the RAM on my machine (all 32 GB) and crashes due to insufficient memory. During my investigation, I discovered the cause of the problem.

In the src/lib/detect.ts module, there's code that loads GeoLite2-City.mmdb:

  // Database lookup
  if (!lookup) {
    // eslint-disable-next-line no-console
    console.log('debug: loading GeoLite2-City.mmdb'); // Code added by me
    const dir = path.join(process.cwd(), 'geo');

    lookup = await maxmind.open(path.resolve(dir, 'GeoLite2-City.mmdb'));
  }

This code is executed a very large number of times during startup, which is why the RAM is exhausted.

I tried adding a debug line after the condition, and here's what I got:

I'm running the latest version in Docker: ghcr.io/umami-software/umami:postgresql-v2.15.1

P.S I already tried updating the maxmind library and it didn't solve the problem

Database

PostgreSQL
