I am currently experiencing the [known issue](https://github.com/elastic/logstash/issues/11051) where JRuby files are not cleaned up in /tmp on CentOS 7.

My temporary resolution has been to set up a cron job to remove these folders. To save others trouble, here is my setup:

I created /tmp/clean.sh, which contains:  
`find . -type d -name 'jruby*' -mtime +1 -prune -exec rm -rf {} \;`

This finds all folders starting with jruby within the tmp folder (Hence the location) older than one day and prunes them. If you have a server that is processing a lot more data, I believe you could swap the +1 for +60s to pick up items older than one minute.

Then, I set up my cron job using sudo to ensure it runs elevated.  
`sudo crontab -e`

Within this file, I have set to run every 12 hours.  
`0 */12 * * * /tmp/clean.sh`

If you have trouble with scheduling cron jobs, I highly recommend crontab.guru. They've listed out all common configurations. For example, [the "every 12 hours" page](https://crontab.guru/every-12-hours).

Anyway, while I'm not new to command line, I'm still much lighter on experience in Linux than I am with Microsoft systems. So troubleshooting this has taken some time, and I wished to potentially save others that time.

Edit: Note that this doesn't resolve any of the underlying issues if you're having a JRuby related issue, this is solely to clean up the tmp folder.
