Hello, I installed the last version of RocketChat (3.7.0) this morning. And since then, the CPU usage increased from 5% to 55%. I don’t know why and I don’t see anything suspicious in the logs. I restarted the server but the problem didn’t resolve. Is there a way to solve this problem or to rollback to the older version ? ### Server Setup Information - Version of Rocket.Chat Server: 3.7.0 - Operating System: Debian 10 - Deployment Method: tar - Number of Running Instances: 1 - DB Replicaset Oplog: Enabled - NodeJS Version: 12.14.0 - x64 - MongoDB Version: 4.0.12 - Proxy: apache - Firewalls involved: ufw ### Additional informations #### Logs rocketchat ```auto I20201001-07:58:29.915(2) Setting default file store to FileSystem I20201001-07:58:34.789(2) (migrations.js:120) Migrations: Not migrating, already at version 206 I20201001-07:58:34.965(2) ufs: temp directory created at "/tmp/ufs" I20201001-07:58:40.553(2) Updating process.env.MAIL_URL I20201001-07:58:40.625(2) Loaded the Apps Framework and loaded a total of 1 Apps!
