Abort any deployment scheduled until this alert is cleared.
Launch additional marketing campaigns which may bring additional pageviews to your site.
Run indexers or additional crons which may cause additional stress on CPU or disk.
Do any major administrative tasks (i.e., Commerce Admin, data imports / exports).
Clear your cache.
Your site may become non-responsive, (if you are not already experiencing a site outage) if you do any of the “Don’t” actions before you have investigated and solved the cause of the alert.
Follow these steps to identify and troubleshoot the cause.
Because this is a critical alert, it is highly recommended you complete Step 1 before you try to troubleshoot the issue (Step 2 onwards).

If in New Relic you see a slow increase in disk usage, try the following options:
Optimizing disk space by adjusting space allocation. For steps, refer to Manage Disk space in our developer documentation. You may also need to request more disk space (contact your Adobe Account Team).
If New Relic shows rapidly increasing disk usage, this could indicate that there is a problem that has caused a file to increase very quickly in a directory. Do the following checks:
Check overall disk space to identify the problem by running the following command in the CLI/Terminal: df -h
After you identify a directory with unexpectedly large and increasing disk usage, you need to check the affected file system. The following example shows how to check the file directory pub/media/. This is the directory Commerce uses for storing logs and big media files. However, you should run this command for any directory that shows unexpected disk usage: du -sch ~/pub/media/*
If the output from the terminal shows a file in one of these directories rapidly increasing in disk usage and you know that the file’s content is not needed, consider removing the file. If you are not comfortable taking this action, submit an Adobe Commerce support ticket.
