Reproduction Example/SDK Setup

my sentry init in 7.118.0

    init({
        dsn: process.env.SENTRY_DSN,
        environment: process.env.NODE_ENV || "none",
        release: require("../../package.json").version,
        serverName: `${cluster.bot}-c=${cluster.id}-first=${cluster.first}-last=${cluster.last}` || "none",
        integrations: [
            new Integrations.Postgres({ module: require("pg") }),
            new Integrations.Modules(),
            new Integrations.FunctionToString(),
            new Integrations.LinkedErrors(),
            new Integrations.Console(),
            new Integrations.Http({ breadcrumbs: true, tracing: true }),
            rewriteFramesIntegration({ root: path.join(__dirname, "..") }),
        ],
        // Performance Monitoring
        tracesSampleRate: 1.0, //  Capture 100% of the transactions
    });

my sentry init in 8.6.0

    Sentry.init({
        dsn: process.env.SENTRY_DSN,
        environment: process.env.NODE_ENV || "none",
        release: require("../../package.json").version,
        serverName: `${cluster.bot}-c=${cluster.id}-first=${cluster.first}-last=${cluster.last}` || "none",
        integrations: [
            Sentry.modulesIntegration(),
            Sentry.functionToStringIntegration(),
            Sentry.linkedErrorsIntegration(),
            Sentry.consoleIntegration(),
            Sentry.httpIntegration({ breadcrumbs: true }),
            Sentry.rewriteFramesIntegration({ root: path.join(__dirname, "..") }),
            Sentry.onUnhandledRejectionIntegration(),
            Sentry.onUncaughtExceptionIntegration(),
            Sentry.redisIntegration(),
            Sentry.postgresIntegration(),
        ],
        // To avoid sending too much data to Sentry, we can reduce the sample rate of traces and profiles
        tracesSampleRate: 1.0,
        profilesSampleRate: 1.0,
    });

Steps to Reproduce

I'll try removing some of the integrations to see what's causing the problem.

Expected Result

A normal memory usage

Actual Result

anormal memory usage

Hey @flav-code thanks for writing in!

We'll look into your issue next week as this week is Hackweek at Sentry (see #13421).

Hi, @flav-code would you be able to provide a memory snapshot with the Node/v8 profiler so that we can look at what is holding the references causing the leak? Feel free to also shoot us an email or twitter dm if you don't want to publicly share it. Thanks!

[flav-code]

I can't give you an snapshot because I have a lot of private information.

[flav-code]

I made a snapshot, I'll examine it and show you
