Message processer method not called in some cases

[svenmueller]

i'm listening for message "ParcelAddedToDelivery". Sometimes the processor method is triggered when i create a parcel in the merchantcenter. But then it suddenly stops working and the processer is not called anymore no matter how much parcel i add. any idea how to track this error down? This cloud also be a problem in the backend or so...sometimes it starts working again when i create a parcel for a different (new) order.

Thx!

I think I have this problem too. I noticed that all new custom objects in the $processor.messages container keep getting the state "lockedForProcessing".
