Recently, been getting frequent OOMs which kill mySQL. Viewing top in Terminal, the mysqld CPU jumps intermittently from 0 then raises to 195% (probably crashes then). I have auto restart so site operates. In PMA, I'm seeing these weird localhost automatic queries (I have 3 screenshots) that are SELECT DISTINCT items against products with Fulltext initialization. I have slow log set, here's a few of those entries, however, the queries run every few seconds, so these are just the longer ones (long-query-time=10):
How to troubleshoot this? I've never seen this before.
