[Zope-dev] Attempt to store an object from a foreign database connection?

[Stefan H. Holek]

Hi All!

My situation is this: When creating CPS sites I sometimes see one of the 
tracebacks appended below.

In its factory method (manage_addCPSSite) CPS creates two External Methods 
(cpsinstall & cpsupdate) inside a fresh CMF portal, and then executes 
these. During execution cpsupdate imports some components from .zexp files 
into portal tools.

What does it mean when "the connection" is "closed"? Where does the 
"foreign database connection" come from in the first place? Is it probably 
not a good idea to run External Methods from inside a factory method?

I can not all too reliably reproduce this but what I do is constantly 
create and delete CPS sites as I am customizing the mentioned External 
Methods. I also noticed that after a restart it works for a while, and then 
suddenly starts bombing out (after approx. 2 minutes). Once it is broken 
the error persists and I have to restart to be able to add a CPS site again.

Happens with Zope 2.5.1 and 2.6.0 on Mac OS X and GNU/Linux

Any hints appreciated,
Stefan
