Unfortunately, HP-UX B.11.23 isn't something easy to find for 
testing.  So I wouldn't expect this can be debugged by anyone 
except you.

My best guess is that the problem is caused by multiple versions 
of socket functions on HP-UX, see this commit for some details (it 
was done after some basic testing on HP-UX B.11.31):

http://hg.nginx.org/nginx/rev/489839d07b38

Though given that 11.23 is quite old it is possible that the 
situation is different there.
