Memory leak when sharding

I'm experiencing a memory leak when using sharding in my bot, obviously memory leaks are hard to debug so I just would like some advice on how to diagnose the issue. The bot slowly rises in memory usage up to 2-3 gbs until it runs out of memory. I tried running heap snapshots, but that didn't provide meaningful results. I've tried using discord-hybrid-sharding and without it, with the same results. I've tried switching tokens to a bot with around 5 servers, and memory usage started low due to having less things to cache, but always grew in memory until crashing. Yet, removing the sharding refactor never had memory climb indefinitely. Has anyone experienced similar issues, I'd appreciate some advice on what to do/where to look.

Cluster.ts

import { ShardingManager } from "discord.js";
import config from "./models/Config";

const manager = new ShardingManager(`${__dirname}/bot.js`, {
  token: config.token,
  totalShards: "auto"
});

manager.on('shardCreate', shard => {
  console.log(`[SHARD ${shard.id}]: Launched`);
  shard.on("ready", async () => {
    console.log(`[SHARD ${shard.id}]: Ready`);
  });
});

manager.spawn({ timeout: -1 })
.catch(console.error);

Im honestly not sure what I did, but it may have solved itself (?) been a busy week so I haven't actually tested much. but memory usage seems normal now
