> If a SystemUsage limit is set on TempUsage, and that limit is reached, that queue enters a state of deadlock where messages need to be removed so new ones can be added, but they can't be removed because the objects are locked.
> I have a patch attached to this issue where the synchronization in StoreQueueCursor and FilePendingMessageCursor is reworked to get around this issue.
