Hello All,

I am trying to test installation on aarch64 - Linux XXXXXX 5.4.17-2136.302.6.1.el8uek.aarch64 #2 SMP Tue Dec 14 12:00:21 PST 2021 aarch64 aarch64 aarch64 GNU/Linux

and following errors appear:

Please, can you share any tips on how to resolve this error?
Thanks a lot!

That means that there is something already in that port. Can you stop whatever is listening there?

Thanks for your prompt reply!

I did some checks but its ok, now I am attaching full log file from the setup

Thanks a lot!

Can you run sudo lsof -i -P -n | grep LISTEN on your host and share the output here?

Looks like I was wrong here. The problem is that redis isn’t starting up…

<jemalloc>: Unsupported system page size
<jemalloc>: Unsupported system page size

@esk8builders can you please run

uname -a
getconf PAGE_SIZE

What distro is this? I tested the aarch64 using the official Raspbian distro.

We use jemalloc with 4096 page size, that is why it fails on your configured page size.

4096
same here, on a standard ubuntu 20.04 on Oracle cloud arm server

Hello Falco, This is standard for [Oracle-Linux-8.5-aarch64-2021.12.14-0] for Ampere server processors

I will try to change to more standard architecture

Thanks for your help!

Hmm so the Oracle Linux kernel was compiled with this somewhat different PAGE_SIZE.

Can you run a debian distro in those Ampere servers @esk8builders ?

This is likely due to the CPU hardware - smaller page sizes aren’t available or are extremely inefficient at maximum RAM

Hi, I’m having the same issue when trying to install discourse via docker on Oracle’s Ampere server, spec is
Oracle Linux Server 8.6
Linux 5.4.17-2136.305.5.4.el8uek.aarch64

Is there a solution now? Any suggestion on what I should try? Thanks a lot!

Did you try using a Debian based os as recommended above?
