Does anyone know what could be happening here? Does writing a file to
tmpfs and then deleting it cause the tmpfs to retain that allocated

Wikipedia tells us that shared memory is used to communicate between programs and between threads in a program. It's created by shm_open and then goes on to say this:

The shared memory created by shm_open is persistent. It stays in the system until explicitly removed by a process. This has a drawback that if the process crashes and fails to clean up shared memory it will stay until system shutdown.

My guess is that one or more of the programs you're using is either crashing or is otherwise ill-behaved and not cleaning up after itself.
