TS SDK Memory Leak

[solserer-labs]

System: Ubuntu 20
RAM: 4GB

Tried with node versions 19, 18 and 16.

The drift client subscription and has a memory leak. Subscribing leads to a constant increase in memory until the nodejs process dies.

Sample code that subscribes and waits. After 10 or so minutes the process has accumulated 300MB more in memory usage.

    const wallet = new Wallet(await getSolanaKeypair("secrets"))
    console.log("Loaded keypair with address:", wallet.publicKey.toBase58())
    const connection = new Connection("")
    const driftClient = new DriftClient({
        connection,
        wallet,
        env: 'mainnet-beta',
    });
    await driftClient.subscribe();
    while (true) {
        try {
            console.log("waiting")
            await new Promise(r => setTimeout(r, 5000));
           
        } catch (error) {
            console.log(error)
        }
        await new Promise(r => setTimeout(r, 60000));
    }
}
