I have nginx server. With following configurations:
32 GB RAM
Intel Xeon E3-1231v3 (3.4)
It is a dedicated server and hosts only one website. Recently, the average load was pretty high (uptime command). I debugged all the php code and there is no bug as it is mostly static website with rewrite mode. It only fetches data from MySql. I used iotop command and it showed the following command was eating all the io.
find /var/lib/php5 -depth -mindepth 1 -maxdepth 1 -ignore_readdir_race -type f -cmin +300 -delete
What does it has to do with nginx or php? How could I stop it? It runs after sometime automatically.
MySql Conf file settings are here.
