No, it normally wouldn't consume anything.

Firstly, /dev/shm is a tmpfs, i.e. a RAM file system, so no Flash
space should be allocated for it ever (unless you swap to Flash).

Now, it usually doesn't even consume much RAM, because as I said
multiple times already: the size of this shm file does NOT reflect the
actual use of RAM, it reflect the use of address space. Use "du" to
figure out the use RAM.

Again:

The file size reflects the amount of reserved address space.

The disk usage ("du") reflect the amount of used RAM.
