Campaign goes to finished status without reaching all subscribers

[antkey1]

Version:

• listmonk: 2.3.0
• OS: Ubuntu 22.04.1 LTS
• Docker: Docker version 20.10.22, build 3a2c30b

Description of the bug and steps to reproduce:

Faced the problem that the campaign ends after reaching only 3 subscribers out of 786210.

I checked several subscribers - all fit the conditions of sending.

Campaign data from database:

select id, uid, send_at, status, type, messenger, to_send, sent, max_subscriber_id , last_subscriber_id , started_at , created_at , updated_at
from campaigns c
where id = 23

Log:

listmonk_app  | 2023/01/25 10:29:42 manager.go:684: campaign (Name) finished

Can you please tell me how to find the cause of the problem?

This is very strange. Could you share a screenshot of the Settings -> Performance configuration?
