That is a knock-on effect of the previous problem:

For some reason, as a non-root user you can't start a thread to service
the incoming connection. Perhaps you have a very small limited number of
threads a normal user can create?

Try making a simple program that uses omni_thread to create some threads
and see if it works. You could try the diner example in
src/examples/thread to see if that works.

That's ancient history. There's no longer any need to do that.

Cheers,
