Hi there - I've reproduced the same problem here on my setup, also on Win NT. Here's what I did, and what happened: 1. I set up a Zope installation (Zope 2.0.0b4 w/ patches from the latest CVS), with an index_html 2. I used Socrates (postcard-shareware testing program) to pound Zope with a pretty reasonably low request rate. 3. I tried accessing index_html through Netscape while Socrates was still testing index_html. 4. Both Netscape and Socrates got no response; the Zope machine had a pop-up dialog on it saying that 'An application error occurred, Exception: Access violation (0xc0000005), Address 0x00f7a88f)' with python.exe (I ran z2.py from the command line with -D, hoping to get a traceback or something)... effectively it looks like the procedure above can kill Zope/ZServer on Win32. One thing that I noticed was it seemed like it was fine if I accessed pages other than the one that was being checked by Socrates - I was able to click around the management screens a bit before having it lock up - when I clicked on the top level folder in the management screen (<pure speculation>probably requiring an access of the same object or objects which were also being accessed by another thread???</pure speculation>) that was when I got no response. Have you found any more clues about this? --Brian Robin Becker <robin@jessikat.demon.co.uk> wrote:

And one other debugging thing to look for: when it's hung, check to see if the process is consuming much CPU.
... ok I don't know what's causing my lockups. I have the 1.9 HTTPResponse etc and I can reliably after around 2000 hits from my torture tester get the win32 ZServer to lock as far as HTTP is concerned. I can use the monitor to see that things are alive in the medusa loop.
My cpu hog thread is responsive (the job queue is empty) and I'm able to add a job and have the server thread go. And the system monitor reports no serious work going on unless I start it. I am unable to get in via netscape.
The interesting thing is that the torture script is also hung so it may be a strangeness related to win9x ie too many requests hanging on the port or somesuch. Killing the torturer doesn't help though.
I suspect that HTTP publication is locked somehow. When it happens again is there anything I can look at to test various/threads etc? -- Robin Becker
