Understanding the “soft rlimits” Warning
- In MongoDB, a warning with “soft rlimits” is a system-imposed limit on the number of open file descriptors that can be accessed by a process or the user and is referred to as a limit.
- MongoDB can not perform even the basic processes such as communicating or withholding other processes without these file descriptors.
- This has led to a serious security breach. Issues like a low limit of opening new connections and files may exist if the limit is set to close.
Checking the Current Limits Before making changes, it is essential to check the current file descriptor limits. We can do this using the ulimit command in the terminal.
ulimit -n
This command displays the current “soft” limit, which is the maximum number of file descriptors a user can open in a single session. We can also check the “hard” limit, which is the maximum value that the soft limit can be set to:
ulimit -Hn
