Maybe... depends on your level of Zope Zen. It's hard to tell which classes should and should not have high refcounts. For example, in your sample output, I know that high numbers of references to ImplicitAcquirerWrappers, HTTPRequests, ZServerHTTPResponse, and RequestContainer objects likely indicate a leak of REQUEST objects somewhere in your code. OTOH, the high number of references to DTMLMethods might be totally normal. But I only know these things because I know Zope maybe better than most folks do, and I just... well... *know*. ;-) It's hard to explain the reasons I know these things to other folks (although I started on something like it at http://www.zope.org/Members/mcdonc/HowTos/PreventAndDebugMemLeaks (unfinished). That said, even if I took a day to finish my unfinished HowTo, the only bit of wisdom that I could consistently espouse given Control_Panel -> Debug output is that indeed you do have a leak. So you'd know you have a leak (which you knew in the first place). How do you fix it? I don't know. ;-) That's where the binary search comes in. Shane's LeakFinder can make the binary search a bit easier by recording states between leakfinding runs, but it's still mainly an exercise in binary search. > The remark, Andre, Chris has written a very nice product, called > AutoLance which helps by monitoring zope's memory usage and restarting > if a configurable threshold is reached. If you can't solve the problem at least treat the symptoms. ;-) - C _______________________________________________ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
