Technical Support

OS Name/Version: Ubuntu

Product Name/Version: AMP v2.6.3.2, built 22/10/2025 11:11

Problem Description:

Creating a rust server take 20 minutes and always crash with out of memory dump
I have 64 gb ram and this is the only thing that will run on it, so out of memory is pretty bizzare. I do not find any memory parameters i can set also.

I am new to AMP it seems to be a great tool by the way

Steps to reproduce:

  • Step 1 - Create Rust Server

  • Step 2 - Check the logs, it will stop by himself after 20 min

  • Step 3 - Checking with htop, still display that i am always all free in ram

    Always happen after this logs:
