[Zope-dev] PLS HELP Zope: hangs + instable

[Eric W. Sink]

Hallelujah!  I no longer feel alone in the world.  Here is the
desperate cry for help which I posted to the world several weeks ago.
The thread contains two further messages, both from myself.

http://lists.zope.org/pipermail/zope/1999-December/015473.html

However, no solution was ever found, and I never discovered anyone
else who could even empathize with my plight.  Until now.  :-)

Since posting my original messages, I modified our z2.py file to
constrain our Zope installation to a single thread.  Since then the
problem has not occurred, but I don't consider that to be conclusive,
nor do I consider my workaround to be satisfactory.

> We've just recently started www.linuxvideo.org with Zope and run into serious problems with our Zope Installation - Zope just hangs after 2-3 days running. :(

> First our configuration:
> 2 x Intel Celeron 433MhZ Processor
> 128MB RAM
> Linux 2.2.13
> Zope 2.1.1-src (we had the same problems with 2.1.0, We've bound Zope to just 1 of 2 ip addresses on our system. We run the plain Zope Server on Port 80)
> Python 1.5.2

> Problem description:
> After some time of running flawlessly, our Zope installation hangs without any error message. If you want to connect to www.linuxvideo.org via your browser you get an endless: "HTTP request sent; waiting for response.". Telnet to linuxvideo.org on port 80 _is_ possible:
> When I "telnet linuxvideo.org 80" and type some gibberish, after some time the Medusa webserver reacts:
> --snip--
> HTTP/None 400 Bad RequestServer: Medusa/1.13

> Content-Length: 136

> My faked request is logged in Z2.log too (2nd line):

> BUT no page will show up in any browser. Zope processes are working normal (no 100% CPU usage, ect.).

> What can we do to prevent Zope from hanging like that again. Do you need some more debugging infos? (Please tell me what/how)
