Brian, Yup, I think I've noticed that as well ... No more wrapper leaking, but DateTime still seems high, and the request related classes still grow. I don't use Plone however, just standard CMF. Right now I'm trying out recipe 14.10 from the Python Cookbook: Tracking Instances of Particular Classes. Hopefully with the ability to "attach" to instances left around through the monitor I can inspect them and find out what's so special about them :) No eureka moment from me yet! :P J.F. -----Original Message----- From: Brian Lloyd [mailto:brian@zope.com] Sent: May 14, 2004 2:56 PM To: Jean-Francois.Doyon@CCRS.NRCan.gc.ca; chrism@plope.com Cc: stefan@epy.co.at; zope@zope.org Subject: RE: Leaking HTTP requests Interesting - I applied LeakBGone to zope.org, and while it did not fix the problem, it did seem to change it in an interesting way. Before, there were far more ImplicitAcquirerWrappers than anything else. Now, I'm consistently seeing ~100,000 DateTimes and ~36,000 PloneFolders after running for about 90 min., and the wrappers stay stable at around 250. Not a clue what it means yet, but I thought I'd share another data point in case it makes someone say "eureka"... Brian Lloyd brian@zope.com V.P.
