### Description

Hi folks,

I use the Cloudron-Platform and installed Rocket.Chat-App on it. All is working fine but Rocket.Chat causes a high CPU load of the server.  
First guess was: I had to rescale the server. So i did it. But the same problem (using now the [CCX13 Cloud Server from Hetzner](https://www.hetzner.com/de/cloud)).

I posted the problem in the Cloudron forum before but there aren’t a solution either: [Rocket.Chat 6.3.0 high cpu usage | Cloudron Forum](https://forum.cloudron.io/topic/9791/rocket-chat-6-3-0-high-cpu-usage)

Anyone an idea?

### Server Setup Information

- Version of Rocket.Chat Server: Rocket.Chat Version: 6.3.7
- Operating System: Cloudron v7.4.1 on Ubuntu 22.04.1 LTS
- Number of Running Instances: 1
- DB Replicaset Oplog: Enabled
- NodeJS Version: 14.21.3 - x64
- MongoDB Version: 4.4.19
- Proxy: nginx
- Firewalls involved: yes → ports 80 and 443 ingoing and all outgoing ports enabled

### Any additional Information

The app log show the following error (more often):  
`=> Healtheck error: Error: connect ECONNREFUSED 172.18.16.54:3000`  
But I don’t know if thats a hint to the causing problem…
