I noticed that recently my RAM was being used up by mysqld.exe. I’m talking 3GB of RAM - I set the max in-memory setting to 2GB prior to this happening, and disabled the enable cache overflow setting. Not sure if this has anything to do with it. Is there any way to limit the amount of RAM this exe uses? I found this post: http://dba.stackexchange.com/questions/53336/mysqld-exe-memory-usage
It mentions adding performance_schema = off to the config file, which I tried, but I could never get mysqld.exe to actually stop running. Every time I try to kill the process it just starts right back up again.
