Did you change your kernel and or other system start information?

tmpfs has a mount option to specify the maximum size. As /dev/shm is
usually for small shared memory regions (POSIX) it gets limited to
smaller size than 50% of available RAM.

Try 'mount -oremount,size=100M /dev/shm' ... but this is all not
Busybox related.
