IRR mirrors de-sync from ARIN or irrd4 bug or ARIN streaming is broken?

Hi folks!

I noticed something unusual today, and perhaps some of you know the answer.

Consider ARIN rr:

$ whois -h rr.arin.net 199.52.73.0/24
route:          199.52.73.0/24
origin:         AS132055
descr:          EY India
admin-c:        IAM12-ARIN
tech-c:         DNSAD85-ARIN
tech-c:         IAM12-ARIN

source:         ARIN

everything looks fine.

Now RADB mirror:

$ whois -h whois.radb.net 199.52.73.0/24
%  No entries found for the selected source(s).

nothing!  I suspect the mirror is out of sync.

Now NTT mirror:

$ whois -h rr1.ntt.net 199.52.73.0/24
route:          199.52.73.0/24
descr:          RPKI ROA for 199.52.73.0/24 / AS132055
remarks:        This AS132055 route object represents routing data retrieved
                from the RPKI. This route object is the result of an
automated
                RPKI-to-IRR conversion process performed by IRRd.
max-length:     24
origin:         AS132055
source:         RPKI  # Trust Anchor: arin

As you can see it returns only RPKI data, and not ARIN. So ARIN data is not
in sync there as well?

However for 199.52.53.0/24 it returns both

$ whois -h rr1.ntt.net 199.52.53.0/24

My question is how and what happened? I suspect whois stream was incostent.
Because if one check todays ARIN DB it surely has the data

$ wget ftp://ftp.arin.net/pub/rr/arin.db.gz -O - 2>/dev/null | gzip -d |
grep -A10 199.52.73.0/24
