Description Radim Vansa 2013-10-16 10:42:43 UTC 
In a situation where a node is losing ownership of an entry (during a state transfer), when the node does a write (and commits that), the change is propagated only to the new owners, the entry is not written locally. However, when it executes read for this key afterwards, it gets the old value as this is directly retrieved from the data container.

Note that the entry should not be written locally if the invalidation was already executed.

This bug was observed in transactional mode, but might not be limited to it.
