issue with a ZODB database conflict error
I'm getting this error on trying to add a new file to a Plone site. Plone 2.1.3 Zope 2.8.7. The object I was trying to add was a PloneExFile. 2006-09-26T19:25:52 INFO ZODB.Conflict database conflict error (oid 0x7b41, class Products.CMFPlone.Portal.PloneSite) at /VirtualHostBase/site/VirtualHostRoot/createObject (1 conflicts, of which 0 were unresolved, since startup at Tue Sep 26 15:15:40 2006) Any ideas? What happens is that on adding the file Zope just egg timers for ages and this appears in the logs. In the end a new file is added but that's only after many many minutes etc -- michael

Far be it for you actually bother googling for "Zope ConflictError" and reading the reams and reams of material that have gone over this before! Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
I'm getting this error on trying to add a new file to a Plone site. In fact this message is just INFO not ERROR and usually it may be safely ignored. Search archives for conflict errors (there was a lot about this).

Thanks for the reply Maciej. What happens is that Zope egg timers for an eternity - around 3-4 minutes then doesn't actually return a success page. However if I then refresh the site I see that a PloneExFile has been added. No good for training :-) I will try out the deadlock debugger. I have a couple of other sites running on the instance using the same ZODB and they are able to add PloneExFiles ok. On 9/27/06, Maciej Wisniowski <maciej.wisniowski@coig.katowice.pl> wrote:

I mean that file is added and Zope finishes his job quickly. If so, then something may be wrong with redirection after this. Have you tried different browser? Firefox instead of IE or something like that?
