No, it shouldn't.  It appears that there is some problem with the
snapshot process on large filesystems in 5.4-RELEASE and perhaps
others, but I don't know how aggressively it is being investigated, or
whether a solution has already been found.

There have been several posts about this in the past month or two, if
you search the archives you might find better information about it.  I
remember there was conjecture about the possible cause (e.g.
insufficient temporary storage space for the inode list), but I don't
remember if this led to a workable solution.
