128GB of ram should be enough to process 1M events. Could you show systemctl status yeti-cdr-billing@cdr_billing and last lines of dmesg

If you want drop events you should connect to CDR database and run:

cdr=# select * from pgq.get_consumer_info();
 queue_name  | consumer_name |      lag       |    last_seen    | last_tick | current_batch | next_tick | pending_events 
-------------+---------------+----------------+-----------------+-----------+---------------+-----------+----------------
 cdr_billing | cdr_billing   | 09:48:56.63222 | 00:00:02.232517 |   1199607 |               |           |              0
(1 row)

cdr=# select pgq.unregister_consumer('cdr_billing','cdr_billing');
 unregister_consumer 
---------------------
                   1
(1 row)

cdr=# select * from pgq.get_consumer_info();
 queue_name | consumer_name | lag | last_seen | last_tick | current_batch | next_tick | pending_events 
------------+---------------+-----+-----------+-----------+---------------+-----------+----------------
(0 rows)

cdr=# select pgq.register_consumer('cdr_billing','cdr_billing');
 register_consumer 
-------------------
                 1
(1 row)

cdr=# select * from pgq.get_consumer_info();
 queue_name  | consumer_name |       lag       |   last_seen    | last_tick | current_batch | next_tick | pending_events 
-------------+---------------+-----------------+----------------+-----------+---------------+-----------+----------------
 cdr_billing | cdr_billing   | 09:49:21.552044 | 00:00:08.12832 |   1199607 |               |           |              0
(1 row)

cdr=#

then you should restart cdr_billing process.
