Runtime Error: Can't start new thread

[ABEHW]

After a while when using Docker image, during Build, when trying to upgrade PIP or install packages I get a runtime error. I've upgrade to python version 3.10 and 3.11 and still getting the same issue.

i get the same error for all availabe versions that are not alpine when trying to build the image on my embedded linux machine on which i wanted to run the server:

It builds fine on my workstation so i assume it is hardware/os dependent.
I will update you when I find a way to it on my embedded linux machine

EDIT:
As i cannot change anything on the system it is supposed to run on, I have resorted to building the image elsewere and moving the build image over to the other machine to run it, which works without problems

This issue is most certainly related to docker and/or the operating system and not this image.
I unfortuanetly am not able to validate that myself, but every resource I looked at mentioned this as the most likely cause.

How about this way?
