Thanks to Geoff, the problem is narrowed to a crash at
self._socket.send() call in the modified ThreadedAppServer.py:401
code below...
print "start loop"
while sent < reslen:
try:
print "<%d>" % sent
val = self._buffer[sent:sent+8192]
print "."
cnt = self._socket.send(val)
print ","
sent = sent + cnt
except socket.error, e:
if e[0]==errno.EPIPE: #broken
pass
else:
print "StreamOut Error: ", e
self._socket.close()
self._socket = None
break
print "end loop"
And the result I get... (before it dumps me to the prompt...)
end loop
start loop
end loop
start loop
<0>
.
,
<8192>
.
,
<16384>
.
So. It reads in what to write... but when it goes to
write to the socket self._socket.send(val) it crashes.
Thoughts as to how to proceed?

| Ah, you're right. I can reliably reproduce the problem (even locally on
| the same machine as the web server and app server). This is on WinNT
| 4.0. It doesn't crash the server, I just get the message "StreamOut
| Error: (10053, 'Software caused connection abort')".
|

| ThreadedAppServer.py around line 407 -- that's where Windows is printing
| the error message. Try adding some extra exception handlers and debugging
| print statements to see what's really happening.
|
| I'll try to reproduce this at home on my Linux box, but since I only have a
| single machine, not a network, I may not be able to provoke the problem at
| home at all.
