[Python-Dev] socket listen problem under aix

[Michael Petroni]

hi!

sorry for posting here as a non-member and non-developer, but i've a 
problem that is (maybe) a bug:

i'm running python 2.2.3 under aix 4.3.3 compiled with gcc version 
2.9-aix51-020209.

subsequent accept calls in the socket library block after a defined 
number of calls depending on the accept queue size. the call then never 
returns, a connection to the server port gets a timeout and netstat -a 
still shows the port as listening.

see the following example code:

----
import socket
queue_size = 6
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(("", 7111))
s.listen(queue_size)
while 1:
	(c, addr) = s.accept()
	c.close()
----

depending on "queue_size" the loop blocks after n calls:

size calls
1	1
2	3
3	4
4	6
5	7
6	9

i've tried the same code on various other systems with different python 
versions -> no problem at all. looks like that some ressources for the 
tcp connection queue are not freed any more.

have i found a bug or did i miss something?

sorry for the inconvenience once more and

thx.
