Clean install version 4.0.0 make huge disk usage.

Description:

Hello,

I did a clean install of rocketchat 4.0.0 5 days ago. in a docker container.

Before, I was on the 3.x branch.

I have found that between 3.x and 4 the disc constantly writes even though no one is using chat.

As soon as I cut the rocketchat container, the disk writes return to their normal level.

Steps to reproduce:

Nothing.

Expected behavior:

Normal hard drive usage

Actual behavior:

Heavy use of hard drive

Server Setup Information:

• Version of Rocket.Chat Server: 4.0.0
• Operating System: Synology
• Deployment Method: docker (docker-compopse)
• Number of Running Instances: 1
• DB Replicaset Oplog:
• NodeJS Version: 12.22.1
• MongoDB Version: 4.4.9

Client Setup Information

• Desktop App or Browser Version: 3.5.7
• Operating System: Windows and Linux

Additional context

The server tells me that there are new messages but as the capture shows, there is nothing.

Relevant logs:

Start by reproducing the reported behavior with Rocket.Chat 4.0.0 in the stated Docker setup, comparing disk writes while the container is running and stopped. Inspect the server and MongoDB activity, since no source files or tests are identified. Done means identifying the source of the writes and confirming normal disk usage when the server is idle.
