+## K6 issues
+
+A recurrent issue with Linus users is that the bash terminal has a low default on the number of files the terminal can open.
+
+`ulimit -Sa` and   `ulimit -Ha` shows the soft and hard limits on the number of files. Running the command `ulimit -n 5000` ups the limit to `5000` allowing the tests to run in that bash session.
