> Read or Write conflict errors? I'm getting the "Key Error" traceback on Reads, but my guess is that the actual "error" happens sometime before the "Key Error", when the ZCatalog itself is corrupted. I am not sure what that is, because it does not generate an error.
However, I see the error when I call ZCatalogInstance.Search(...), and only when the Search includes objects that are corrupted in the ZCatalog. > Are the objects modified at the same time by other threads? I'm not sure about this. I'm running ZEO, and in general, I think I can cause the error when I am the only user on the system, only issuing one request. However, I'm getting another ConflictError when I try to set an attribute value of a ZODB object during the execution of a script, and I'm told that may be because there is a problem accessing the same object from multiple threads. Is there a good article that you know of that I could find out more about thread-safe programming in ZEO?
