[ixpmanager] IRRDB PREFIX FILTERED - possible to see reason?

Hi Folks,

I'm working on getting my AS added to a 5.7.0 installation, and for some 
reason every prefix I advertise is being filtered.  I'm having trouble 
determining why.
Other members are able to advertise prefixes, and I'm receiving those 
prefixes so it seems like it's something specific to my member info.
I have tried both my AS-SET macro and my ASN and both produce the same 
result.  For simplicity I'm using my ASN in these examples.

mysql> select id,maxprefixes from cust where autsys like '14818';
+----+-------------+
| id | maxprefixes |
+----+-------------+
|  8 |         100 |
+----+-------------+
1 row in set (0.01 sec)


mysql> SELECT @IRRDBID := irrdb FROM cust WHERE id = 8;
+-------------------+
| @IRRDBID := irrdb |
+-------------------+
|                23 |
+-------------------+
1 row in set, 1 warning (0.00 sec)


mysql> SELECT * FROM irrdbconfig WHERE id = @IRRDBID;
+----+----------------+----------+--------+--------------------------------+
| id | host           | protocol | source | notes                          |
+----+----------------+----------+--------+--------------------------------+
| 23 | whois.radb.net | irrd     | ALTDB  | ALTDB Query from RADB Database |
+----+----------------+----------+--------+--------------------------------+
1 row in set (0.00 sec)


$ bgpq3 -Al test AS14818 -S ALTDB

$ bgpq3 -S ALTDB -Al pl -j AS14818

     { "prefix": "63.229.162.0\/24", "exact": true },
     { "prefix": "63.233.220.0\/23", "exact": true },
     { "prefix": "65.19.0.0\/18", "exact": true },
     { "prefix": "65.19.0.0\/18", "exact": false,
       "greater-equal": 24, "less-equal": 24 },
     { "prefix": "192.12.12.0\/24", "exact": true },
     { "prefix": "207.225.52.0\/24", "exact": true }
] }



$ sudo php artisan irrdb:update-prefix-db 14818
Cyber Mesa: [IPv4: 70 total; 0 stale; 0 new; DB updated] [IPv6: 1 total; 
0 stale; 0 new; DB updated]


I'm advertising 65.19.0.0/18 and 65.19.10.0/24 to the route servers 
currently.  Both prefixes are being filtered, with for following 
communities applied:

14129:1000:3RPKI NOT CHECKED
14129:1101:9IRRDB PREFIX FILTERED
14129:1001:1002IRRDB PREFIX EMPTY

Is there a way to interact directly with irrdb to verify the query it is 
doing as well as what it returns?

Thanks,

Tim Densmore
