    So, I host a website for a customer and their REDIS database is allotted 16gb. I thought this would be very sufficient.

    However.....

    What can I do to investigate why it is consuming so much?

    @privsec wow, that is quite a bit. Does the website use redis? How? Note that core wordpress itself doesn't use redis, so the use has to come from some plugin or website code.

            @privsec If you restart redis, does it's memory usage go up again?

                @privsec Does disabling (not uninstalling) the redis plugin cause the site to break ? I would test this in a cloned website maybe.

                    Sorry for the delay

                    So I tested the site and disabling the redis cache doesn't appear to break the site.
                    The pages load, the images load, the navigation works, user accounts work.

                    Who could I pay to have them look into the redis cache issue?
                    As there has to be a reason it is using that much space

                        @privsec odd. Try reducing it even further? I shouldn't really need anywhere like that much.

                          I reduced it even further, it is still functioning without any issues.

                            @privsec 512mb is the highest I've got any of mine set, and that's mostly just me ramping up things for Nextcloud in the hope it somehow speeds it up. In reality it's not even using half of that. Most I've got on any WordPress website is 256MB. But again, seemingly not even using half of that most of the time. So strange that you're went up so insanely high.
