Out-of-Memory crashes with Mempool (v3.2.1) on 8GB Intel NUC - StartOS v0.3.5.1

Hi everyone,

I am looking for some advice regarding an Out-of-Memory (OOM) issue with Mempool on my setup. The strange thing is that this only started happening recently; it used to run without any problems in the past. I really don’t understand where this is suddenly coming from, especially because I have another node with the exact same hardware specifications and software versions, and that one runs perfectly fine without any memory issues at all.

Here are the details of the crashing node:

  • Hardware: Intel NUC, 8 GB RAM, 2TB SSD, i5

  • OS: StartOS v0.3.5.1

  • The Problem: Mempool (version 3.2.1) causes Out-of-Memory (OOM) crashes and completely fills up my RAM within a few hours.

  • What I’ve already discovered: The process refuses to listen to manual SSH commands to limit the RAM. StartOS continuously forces the startup with node --max-old-space-size=16384 baked into the wrapper scripts, which obviously crashes my 8GB system.

  • Sideload failed: I already tried to sideload Mempool version 3.3.1 (which supposedly fixes the memory limits for 8GB devices), but the .s9pk file gets rejected. I suspect this is because the new package is built with the new SDK for the upcoming StartOS 0.4.0.

Does anyone know a workaround to limit the Mempool memory size on StartOS 0.3.5.1 without the system overwriting it on every restart? Or is there any other temporary fix to keep my node stable with 8GB RAM until 0.4.0 drops?

Thanks in advance for any help!

Try this:

  1. Go to Mempool → Actions → Indexing and Performance
  2. Turn off all indexing toggles (Block Summaries, Goggles, Audit, CPFP)
  3. Set Performance Profile to Low-CPU
  4. Restart Mempool

Backend heap size is dynamic and the extra indexing uses a lot of it.

Thanks @Jesse ! The thing is that I am running StartOS 0.3.5.1 and the latest version of Mempool that I could run is 3.2.1~3. Newer versions are unavailable for me to install in Marketplace.

When I go to Actions, the only option that I have is Uninstall, no other options.

Any thoughts on why I am only able to see Uninstall? And how I could (re)activate the other Actions?

Few more hours and it will probably be again OOM:

The latest releases are for StartOS v040 beta. They won’t work on 0351.
