Push notifications sent twice?!


We’re seeing unexpectedly high push notification usage, and possible double sending of push notifications in our log.

In light of the upcoming paid push notification change, this is critical for us. Some numbers for background:

  • about 200 registered users
  • 50 active
  • 16000 Push notifications this month
  • no bots that send lots of messages
  • just two broadcast-channels with sporadic messages

Server Setup Information

  • Version of Rocket.Chat Server: 3.7.0
  • Operating System: Ubuntu 20.04
  • Deployment Method: docker
  • Number of Running Instances: 1
  • MongoDB Version: 4.0
  • Proxy: traefik
  • Firewalls involved: yes

Any additional Information

A snipped of our debug log. IDs and names have been changed. Is it normal that these push lines appear twice with the same ID?!
