there's 4 days of delay now.

the status says

 st_origin | st_received | st_last_event |      st_last_event_ts      |
st_last_received |    st_last_received_ts     |
st_last_received_event_ts  | st_lag_num_events |      st_lag_time

33 | 4 days 11:27:59.004091


and the table is already filled up like a 10GB in size.There definitely
is more than 33 lag_num_events

What do I do? do I need to be concerned about that number?
