    I keep getting the following error reported from cPanel
    I am familiar with the following thread
    mysql-db-usage.json missing

    I used to have a second UID of 0, but I have since deleted that user. I have also disabled Named Service Cache, but I still get these errors intermittently. If I run the db update by hand it runs successfully. Any ideas?

    Could you open a support ticket using the link in my signature so we can take a closer look? You can post the ticket number here so we can update this thread with the outcome.

    Thank you.

    Just to follow up for anyone else having this problem, it turned out to be duplicate cron jobs that somehow got created when I had another user with UID 0. The duplicate user had the same cron jobs as root, and they were running at the same time. This was causing all sorts of intermittent errors. Removing the cron jobs appears to have fixed the problem, so if you are experiencing something similar, take a look at the cron jobs you have for each user.
