Unless it has been fixed the UFS based stores also have an implicit
limit on cached entries somewhat less than 4KB (whole meta header need
to fit in first 4KB). Entries failing this gets cached but can never get
hit.

For Internet host names the limits are 63 octets per label, and 255
octects in total including dot delimiters.
