Erik Salter commented on ISPN-4693:
-----------------------------------

Yes, in my prototype (using the aforementioned implementation), I use the completedTxTimeout value.  I defaulted it to 60 seconds in the 6.0.x branch to keep the default greater than the transaction manager timeout.

> Consider the following case:
> 1. A prepares a transaction for key K on nodes B and C.  
> 2. The primary owner B acquires and registers this lock.
> 3. The cluster partitions and A,C remain in partition one, and B in a separate partition.
> 4.  The transaction rolls back.  However, since B left the cluster, the rollback will not be sent to B.
> 5.  B rejoins the cluster.  It still has a lock acquired for key K.
> This can lead to a lock being acquired indefinitely.
