I see nothing here that could cause Emacs to spawn too many child
processes for native-compilation: you limit the number of simultaneous
sub-processes to 4, which shouldn't be a problem.

So I still think you should try preparing a reproducer for that
strange error message.  When it happens, could you perhaps see how
many network connections does Emacs have (with, for example, netstat)?
