[Zope-dev] Zope 2.X Session problems

[Kris Erickson]

No, that's not the problem;
in THEORY that's what is happening, but in reality there is no way that 
this is the case;
We just unrolled a registration system with participation rates at or 
around 100 to 200 participants per month;
At any given time, monitoring the session data container, there are *at 
most* 1 or 2 items in the transient object container--EXCEPT when it 
spikes...

The problem is of course, when it floods, the 
MaxTransientObjectsExceeded error occurs site wide (the whole site 
crumbles and returns the error); because it's just passing back to 
Exception, there aren't really any useful details that get carried 
forward to the log (why it occured, last script that executed it, etc).

So, question--is there a way for these errors to occur internally (i.e. 
an improperly looping script setting null values into session, on-error 
demanding that session create a new object to try it again, ad 
infinitum), or is it possible that an external barrage of requests 
(denial-of-service?) is flooding the transient object container?

ideas?
