I'm trying to understand how Conflict Resolution works. The first step will be change my DirectoryStorage for a FileStorage and try again. As you say, I seems that Zope retries the request 3 times when a ConflictError is raised, so it should work in my case. If not, I will try to debug and see how not, or perhaps disabling low conflict flag. If, at the end, it countinues crashing, I will store my data in persistent subobjects.
