[Zope] Leaking Acquisition.ImplicitAcquirerWrapper

[Jean-Francois.Doyon at CCRS.NRCan.gc.ca]

Hello,

I'm not familiar enough with the acquistion wrappers to know what might be
causing this, but it looks like my refcount for
Acquisition.ImplicitAcquirerWrapper grows out of control !

Acquisition.ImplicitAcquirerWrapper 7190 120012 +112822
This is over ~27 hours ... Normally if I stare long enough at it it seems to
be happy hovering in the 15-20K range ... I walk in this morning and see
this.
It's not the first time either ... I've noticed on a few occasions this
occuring and the refcount topping 200K ... And Zope's memory usage growing
and growing, even though the database info shows the same number of objects
in cache, and the same number of ghost objects.
I'm not sure how "consistent" it is however ... I'm wondering if there's
some specific even that triggers this leak ... It seems table in the
minutes/hour after restarting.
The other thing is I'm quite certain I do nothing "weird" as far as
acquisition goes.  The only thing I do is use aq_explicit in a few places,
either in Python code or in PT's.  Other than that, I never mess with it.
Can anybody suggest ways to find out where this might be coming from?  If
they were some of my own classes I'd have an idea ... but in thise case ...
Any help would be most appreciated, this is seriously hurting the
stability/performance and uptime of our site.

I'm using Zope 2.7 w/ python 2.3.3 on RH7.3 with 
- CMF 1.4.2
- TranslationService
- Localizer
- mxmRelations
- ZPsycopgDA

And my custom products

Thanks,
