We utilize this widget to help filter down attributes however it seems to creating heavy, uncacheable queries. It is causing the PHP max_execution_time to be hit which creates a high CPU usage and then ultimately crashing the whole server.

I believe I solved my issue. It was related to this but not the root cause.

After painstakingly trying to debug it seems that there was traffic, probably from a bot scrapper, constantly scanning the filter queries “?filter_” and since it hits the DB, it would doing upwards of thousands of scans so it caused heavy RAM usage, high CPU, and caused the DB to eventually crash. I put in place on our Cloudflare setup to block the scrappers and that stopped the issue. The screenshot I attached shows the traffic seconds after putting the block in place.

Edit: Forgot to mention but since this was scanning those queries so much it was difficult to get the debug log to catch anything since by the time I would restart services, the server would almost immediately crash again. I put in some heavy limitations now to hopefully prevent this in the future.
