Sorry, I indeed misunderstood you.
Could it be that jffs2 requires a minimum granularity for file system sizes? Probably the size needs to be a multiple of the eraseblock size?
$ factor 5824 5824: 2 2 2 2 2 2 7 13 $ factor 5884 5884: 2 2 1471
I.e. the former is a multiple of 64 (KiB), the latter is a multiple of 4 (KiB).

Sorry, I don't know.
