> There is an issue with stale locks when a new node joins a running cluster.
> There are three caches all using eagerLockSingleNode=true with the transaction running on the primary data owner.  The local locks for the affected keys are acquired, and the prepare is sent to the backup owner.  During this time, the new node is detected and joins the cluster.  The transaction times out waiting for the transaction lock, and a rollback is attempted.  Whereas the local keys are unlocked, the remotely-acquired locks never release.
