Hi,

I am trying to use oprofile to sample a running process. The process takes 100% CPU, but still there are no samples from it in oprofile (just no-vmlinux, some daemons, and opreport itself get sampled)
However, if i start the process *after* starting oprofile (with opcontrol -s) - the process *does* get sampled.

I am using the default oprofile which comes with centos 6.2 - 0.9.6-21, kernel 2.6.32-220.el6.x86_64.
Tried to compile 0.9.7 from source and use it, but still get the same result.
oprofile log does not show any buffer overflows, by the way.

Thanks,
