I think I may have subsided it for not at least... I raised the memory up even further and then things stabilized, I then cleared the redis cache from the site and reduced the memory on the associated redis service, and so far it's good again. Early times though, will continue to watch. Also switched out one of the Rank Math SEO plugins with Slim SEO as it was something I've been int he middle of a few client sites anyways, so figured I'd jump and do it here as Slim SEO is quite a bit more lightweight then Rank Math, hoping that'll help a bit too.
When it was there, it was using about 800 MB at the time. It's down to about 100 MB now, back to where the other sites are.
