 Description   
  1. Size of our MongoDB database is 300Gig but the memory usage is steadily  increasing and we have to stop and start the MongoDB to free up the memory. Currently the memory usage is at 414Gig after only 5 days and increasing.
  2. Is there a way that we can trace who is accessing and which user is being used.

Hi ian.dauncey@bankzero.co.za,

Unfortunately, no current version of MongoDB (community or enterprise) is supported on Ubuntu 20.04 with the s390x architecture at this time. Additionally, we have stopped releasing Community versions of MongoDB on s390x as of 6.0; newer releases are currently only available for enterprise binaries.

Given that this is unsupported, investigating this as a server bug is not within our means at this time (and likely wouldn't yield a fix). For this issue we'd like to encourage you to start by asking our community for help by posting on the MongoDB Developer Community Forums.

If the discussion there leads you to suspect a bug in the MongoDB server on a supported version, then we'd want to investigate it as a possible bug here in the SERVER project.

Can I ask,

  1. if there is a way to increase the log level,
  2. if the memory pinn settings is correct, as a way to try and manage the memory run away being experienced.

Any updates on this issue. Not sure what additional information is required as the memory slowly increases day to day. Currently the memory usage is at 715GB
