Summary: socket failed then compiled with treads 

Initial Comment:
Operating System HP-UX 11.0 (64 Bit)
I tried to compile Python 2.1.1 this thread support.
Doing so, the tests 
test_socket and test_asynchat both failed
with "(9, 'Bad file number')"
The test_socket succeds if I compiled python without
threads, so I think it's an thread-problem.
The thread-test istself succeeds.
I think also, that python is correctly linked against
libpthread.
The same Problem occurs this Python 2.2.b1.

the complete compiler line used to link together the python 
binary:
gcc  -Wl,-E -Wl,+s -Wl,+b/mosquito/python/lib/python2.1/lib-
dynload -o python \
Modules/python.o \
libpython2.1.a -lnsl -ldld  -lpthread   -lm  

The compiler I used is gcc 3.01.

I tried it out with the cc from HP - the same effect

After installing the Kernelpatch PHKL_25475, wich supersedes
both PHKL_23842 and PHKL_20942 the failure remains the same

Can you please also check whether the patches PHKL_23842 (or
equivalent) and/or PHKL_20942.

The patch titles are
PHKL_23842 s700_800 11.00 
  signal,threads,spinlock,scheduler,IDS,q3p 
PHKL_20942  s700_800 11.00 
  signal, nanosleep, spinlock, scheduler

It appears that HP-UX has a number of bugs where signals,
forking, and other aspects of the operating functionality
stop working in the presence of threads. If you don't have
these patches, it would be good if you could try to install
them, and report back whether it changes anything.

Notice that HP apparently has a number of patches with these
titles; they seem to be intended for different machines.

What compiler are you using? Can you please report the
complete compiler line used to link together the python binary?
