Beyond what you already know (logging; copy the database and work on  
another software instance; temporarily enable the debugging skin; run  
ZEO and connect via zopectl debug to the database) there might be  
another trick available.  In Zope 2 there is a handy Medusa-based  
trick similar to the basic capabilities of Twisted's manhole I used  
quite a while ago for this.  I can't find any reference to it in  
zope.app.server though: anyone know if this made it to Zope 3?  (Jim  
would know but is off-line still for another week and a half.)  It is  
supposedly pretty easy to implement, because you are basically  
leveraging Medusa, but that's hearsay.
