[Zope-dev] Lowlevel python/Zope Errors: asyncore.py and others...

[Dario Lopez-Kästen]

Hello!

I have a serious problem with Zope. We repeatedly get the following kind of
errors:

2001-09-05T13:45:12 ERROR(200) ZServer uncaptured python exception, closing
channel <zhttp_channel connected XX.XX.XX.XX:1186 at ab1174 channel#: 10
requests:5> (
socket.error:(32, 'Broken pipe')
[/usr/local/zope/dist/Zope-2.4.1/ZServer/medusa/asynchat.py|initiate_send|21
4] [/usr/local/zope/dist/Zope-2.4.1/ZServer/medusa/http
_server.py|send|414]
[/usr/local/python-2.1.1-no_pymalloc/lib/python2.1/asyncore.py|send|330])

and

2001-09-28T14:09:40 ERROR(200) zdaemon zdaemon: Fri Sep 28 16:09:40 2001:
Aiieee! 28590 exited with error code: 138

(error code can also be 139, 256

and

and a lot of these:

------

Our Zope usually locks up big time when this happens. If anybody has some
asyncore.py zen to share and can explain what is going on? We are using
transparent Folders, dunno if it is related to that (I am blaiming most
everything on transparent folders these days ;-).

I found some info on google, suggesting this is an old problem:

with Zope 2.1.6

http://www.zope.org/Members/tseaver/Projects/HighlyAvailableZope/Zope%20h=
ang
ing%20%28poss.%20threads-related%29

and Zope 2.3.1

http://aspn.activestate.com/ASPN/Mail/Message/zope-Dev/531379

We are using the Zope 2.4.1 source release with Python 2.1.1, no pymalloc.
IE Clients.

Thank you for any input.
