its hard to say... you might check which processes the CPUs are running. I'm not familiar with sar, but top and ps let you know which are the processes consuming most CPU/memory.
if it's httpd, then you're right, cakephp is consuming all those cpu cycles. alas, you may check for invalid redirections - I once had this faulty app that kept on redirecting endlessly to the same page, and it went just like your machine did. i'm running 10 cakephp apps on production level (~30.000 hits/day) since the days of cake 1.1 and, except for the above, never had any problem like yours. dfcp On 23 out, 14:49, airween <airw...@gmail.com> wrote: > Hello Cake Users, > > I'm new in Cake - exactly I'm not a Cake user/developer, I'm a system > administrator. > > System is a LAMP enviroment, hardware is a HP DL380, with two CPU, > every CPU has 2 cores. > > I've a site since few weeks ago - since then the CPU utilization isn't > above 100%, but usually over 200%. > > I've created a controller, which does "nothing": it contains just a > simple index() method, which's empty.
