hi guys, i have a problem.
i have a high end server - dual quad core xeons, 16 gb ram, 4 x 120 gb
ssd's in raid 10, and a gigabit pipe. i only host 1 site on it, and from
time to time the php simply locks up, restarts, and during that time,
the users experience 5-10 seconds load times on pages.
i have around 1000 1500 concurrent users at peak times on the website.
here's what happens in the php-fpm.log:
some of those scripts that you see as executing slow, are like 4 - 5
lines of code, so it's pretty impossible to be a coding issue.
here is my php-fpm.conf:
if you guys couuld help me shed some light on this i would much appreciate.
