ISSUE:
We are periodically seeing a MariaDB query that runs that appears to be so memory-intensive that it requires MariaDB to create a bunch of temporary tables. It creates so many that the temporary tables fill the hard drive and the website crashes.
Line prior to the query: Sort aborted, host: localhost, user: root, thread: 1181,I think the rest of the query is cut off in the MariaDB log, but you get the idea.
Help!

- I've already consulted Bitnami, the stack vendor we use, and they think it's a query related to some Joomla-specific function.
- I've disabled the third-party indexing component, so it's not them.
- This doesn't appear to be a CRON job; I already checked that list.
- The crashes occur at different times of the day, so we're at a loss as to how to track down the source.
