[Zope] ZServer Must Be Continually Re-Started
Fri, 11 May 2001 15:22:05 -0400
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
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.
