failed to create new OS thread (have 2 already; errno=22)

I'm trying to build https://github.com/rodolpheche/wiremock-docker multi-arch from my M1 Mac.

The amd64 build gets the following error:

I'm sure this is somehow caused by Qemu but thought I'd check here if there's any way of resolving?

[tianon]

Yeah, this is definitely caused by QEMU's user-mode emulation, which Go unfortunately doesn't officially support. 😞

(I'm not aware of anything that can be done here to fix it.)

[ciaranmcnulty]

Guess I need to look at other options - thanks for the quick response!

[pramttl]

This probably needs to be reopened so someone can suggest a solution for this. I ran into this on Mac M1 too.

[ciaranmcnulty]

It may be something to raise upstream with Qemu or Go?

[ciaranmcnulty]

Actually... updating to gosu 1.14 has fixed this in my case I think
