I have install FreeBSD and i use Nginx for run my website on this webserver.
All working good and the server running from 2month..
Today when i visits my site i have see Nginx Gateway Error 502..
and from shell i run top command and all processor are using 0% of cpu but use the normal ram, with the process php and sql and nginx active but all at 0% of server usage.
all is stopped..
and I don't know why and how happen..
I need a person that optimize the configuration of the server.
now the load average is about 40.
the cpu are running hight.
i have Xeon [url removed, login to view] 8GB ram 200Mbps Raid1 750GB
i have 4 sites and i have 40.000 visits by day.
i need to optimize the php, nginx, sql configuration to load less the server and NEVER crash or go slow..
Thanks for read this post.
