Note that there is probably not one single cause (or solution) for all of the reported "Zope hangs on me" issues. The requestprofiler module (part of the most recent Zope CVS checkout in the /utilities directory) is a reasonable place to start to try to track down a pattern to the hangs. I've put it up separately at http://www.zope.org/Members/mcdonc/HowTos/DEBUG-LOG/requestprofiler.py so people can make use of it before 2.4 comes out. Make sure to read the documentation it has available via the --help switch. You need to turn on "big M" logging (via the -M switch in z2.py) to have something which the script can parse and profile. - C ----- Original Message ----- From: "Will Dennis" <willd@p-wave.com> To: <zope@zope.org> Sent: Friday, May 11, 2001 2:30 PM Subject: [Zope] ZServer Must Be Continually Re-Started
Hello,
I have the same (?) problem with a site running on our Zope server (Zope 2.3.0) -- The site just hangs from time to time (the Zope processes are still running, and not taking any more memory than usual, but ZServer is not responding to GET requests.) A stop/start cures the problem (until it happens again.) This site is a popular site, and gets spidered a lot, so I wonder if it is a thread consumption problem. I have written a Python script to monitor a Zope installation (authored it for just this problem) that is available from my Zope.org page, http://www.zope.org/Members/willdawg .
I'd love to know why this occurs, if someone figures it out...
Thanks,
