This issue is observed on cs6377 (46FC Tag). The cluster is 0f 70 nodes and 2
checkpoint applications run on each node. The application running on the active
controller creates the checkpoint, while the applications running on other
nodes open the same checkpoint and use them. After sections are created,
written and read from all the applications finalizes the handles used. The
retention duration of the checkpoint is specified to a minimal value of 1000
nanoseconds.
/dev/shm on the active controller after the applications exited.

When the same checkpoint name is being tried created, checkpoint service is not
creating a new replica in the shared memory.
