https://community.graphisoft.com/t5/Teamwork-BIMcloud/BIM-Server-19-mongod-exe/m-p/254600#M1122 mongod is the database process that BIMserver/cloud is built on. Seems like you've run into some bug. Don't have a solution, but for reference - our BIMcloud (v21 on Windows 10) server with 14 active projects and over 60 users only uses 24,8MB of memory.

It will be regenerated. <BR /> <BR /> Besides that I recommend to update BIM Server to 9001.
