Hello,

 

I am trying to look deeper into “libphp5.so” that is using up a lot of the CPU. When I run opreport on “libphp5.so” I get (no symbols).

I am disappointed as I was hoping to narrow in on the problem of the high CPU usage. Could this be because I am using the “no-vmlinux”

option when starting oprofiled? Any help would be great!

 

Thanks
