That is the maximum allowed value in dbmgui.

Anyway, after setting Zope to be single threaded, I have not had any segfaults. Tada: You made sure that one connection will get used and you won't get stale ones being timed out and then randomly selected for use at some later point ;-) Get rid of the connection timeouts, and you should be fine for multi-threaded Zope.

Unfortunately, I don't think making the hotfix any better is going to be easy; it's still a product which is initialized after some of the affected code has been loaded and possibly used. Since 2.7.2 should be coming out very soon, I'm not sure it's worth the additional effort to elaborate the fix any further. I'll ask around here at ZC to be sure; others may disagree with me.

[Zope-dev] Zope Package Scripts
Hi, i've just compiled the windows version of Zope 2.7.2 for release. Since the 2.7.1 release I'm a bit annoyed that the resulting final packages get a -0 as a minor release number, which looks awful IMHO. Could someone make the sdist scripts not do this?

Acquisition wrappers are not picklable.

This does not return a wrapped instance.

Your "I" is not wrapped. The problem must be somewhere else.
Almost surely, the problem is the passed in "user" object which
is an acquisition wrapper and therefore cannot be pickled.
