 Status: Pending => Resolved

I am resolving this issue as the originator has not responded.  It is also likely that this was a symptom of with the "trashcan size" bug in Python 2.1.2 and lower and/or a stack size problem with Python on FreeBSD.

Is this behavior still evident under Zope 2.5.1/Python 2.1.3?

Workaround:
Move the either block into a Python Script, and call the script from ZPT.

items=LazyFilter(sequence.sort(sequence, sortkeys),skip='')

for item in items:
  """ output html here """
  print 

return printed

Is it normal to have refcounts this high when I'm the only one using the site?

The cAccessControl.c fix didn't work.  Also, I'm getting various messages that look like this in dmesg:

There is a patch to cAccessControl.c in CVS; try checking out the latest version of lib/python/AccessControl/cAccessControl.c from cvs.zope.org and rebuilding Zope.  This patch will be included in Zope 2.5.1 beta 1, which will be released this Friday, February 15.

running Zope with only one thread helps, but still restarts after a few refreshes.  If contentValues contains Folders and/or Files, Zope restarts.

The following code in local_html on a CMF site causes Zope to restart when viewed via index_html:

<span tal:define="raw_items python: sequence.sort(here.contentValues(filter={'Type':( 'File' , 'Link') } ),(( 'Title', 'nocase', ), ), );
items python: auth_filter( raw_items, skip='' );">

It works fine if I directly view local_html.
