We tried that approach as well with little success. Just pass in the identifier you need and don’t try to pass EOs across thread boundaries. Refetch the EO inside the thread and everything will be a lot happier

But inside the quartz job I create a new editing contenxt use editingContext.faultForGlobalID to bring those objects into the local editing context, and then I dispose that editingContext in a finally block. Is disposing editingContexts what you mean by cleaning up after myself, or is there more to it?

That is a good way to shoot yourself in the foot. Just pass in identifiers to your thread and refetch them in the scope of the thread and clean up after your self inside the thread.

I have a thread dump which I have removed duplicates from and cleaned up a bit. It seems that a lot of threads are BLOCKED waiting on the EOObjectStoreCoordinator.lock() call Deadlock Detection: No deadlocks found.
