Server suddenly maxes CPU and logs show endless php-fpm[4834] child exited signal 9 warnings.

Subject basically says it all. Server has run great for a few years now. But suddenly started maxing out CPU usage and becoming unreachable until a forced restart. I now reboot the server when I get home from work and it works until the following morning when I'm leaving and suddenly nothing works on Home Assistant since it fell into the same loop. I can post more logs when I get back home. Any ideas would be greatly appreciated as I'm out of them. Doesn't seem to point to any specific service or docker either that can account for the resource usage. Not Parity checking or file transfers either. Plus most of the usual io wait culprits are on exclusive shares anyhow as I had similar issues about a month ago so I implemented those changes. Ran great for about a month and a half and now this issue. 

This is the log entry on repeat

 php-fpm[4834]: [WARNING] [pool www] child 9518 exited on signal 9 (SIGKILL) after 12.639217 seconds from start

Anyone? I have uninstalled almost all my plugins and disabled so many Dockers. Nothing stops it. Will run for a day then the above warning and down it goes maxed out and unresponsive. Server has run so well for so long (months of up time) and this just came out of the blue.
