 Service failures can occur for various reasons, including unhandled exceptions, memory leaks, port binding issues, or OS-level disruptions such as resource exhaustion. All failures are logged with their relevant timestamp, source, and last output within the `/var/log/services` directory for the given day in the format `YYYYMMDD.txt`.
 
 To disable this auto-repair mechanism, comment out the relevant line in the source `.setup/submitty_crontab` file within your repository. Since the crontab is auto-generated during installation, any changes must be followed by a re-run of `submitty_install` to persist them.

 The `submitty_daemon` user runs a variety of other scripts, such as [sbin/send_email.py](https://github.com/Submitty/Submitty/blob/master/sbin/send_email.py) to send pending emails every minute.  Console output from these scripts can be emailed to a sysadmin to help ensure that errors can be reported and addressed.
 
 The first line of the relevant script should be set as `MAILTO=` with a valid email address, as shown below.
