Queue - Event are stored in queue tables i.e queues. Several producers can write
into same queue and several consumers can read from the queue. Events are kept
in queue until all the consumers have seen them.
Maybe you have some inactive consumers holding a event tables.
qadmin -h <root_node_host> -p 5432 -U postgres -d <database name> -Q <queue name>
Use 'show help;' to see available commands.
copy output of show consumer command
show consumer;

Thanks Rene, I found only one "idle in transaction" and it dates from
just a couple of minutes ago, so, the reason of huge event table must be
something else.
By looking at the event_1_1 table I found records from march, but
londiste3 status shows everything is already in sync:
nodo_master (root)
| Tables: 146/0/0
| Lag: 0s, Tick: 1112197
+--: node_esclavo (leaf)
Tables: 146/0/0
Lag: 0s, Tick: 1112197
So, what if I manually delete old events?.
