Load average in squeeze too low
sorry, not yelling, its just copied from a bug report and this prob is driving me crazy... ran stress --cpu 4 on a xeon and no problem the load went up to 4, but running mysql server for example the load is almost 0.00, where the same mysql server with same throughput gets 0.8 on another lenny server

help!!! ideas?

EVER SINCE UPGRADING TO SQUEEZE, LOAD AVERAGE IN TOP IS INCORRECTLY
REPORTED AS TOO LOW THAN IT REALLY IS. THIS PROBLEM IS PRESENT IN THE
DEFAULT SQUEEZE KERNEL, AS WELL AS UPGRADED 6.38 KERNEL. THIS PROBLEM
DOES NOT EXIST IN 2.6.26-2-amd64 LENNY. THIS PROBLEM HAS BEEN
REPLICATED ON MORE THAN 1 SERVER. DOWNGRADING TO LENNY KERNEL FIXES
THE PROBLEM. EXAMPLE: SERVER ON LENNY RUNNING 0.80 0.70 0.60 LOAD
AVERAGE LATER REGISTERS 0.00 0.02 0.05 AFTER UPGRADE DURING THE SAME
SERVER LOAD THROUGHOUT THE DAY. SERVER IS RUNNING MYSQL, PROBLEM ALSO
EXISTS RUNNING PHP WEB SERVER. PROBLEM HOWEVER DOES NOT SEEM PRESENT
DOING OTHER TASKS, SUCH AS COMPILING OR GZIPPING.

globus-gridftp-server-setup-chroot

GLOBUS-GRIDFTP-SERVER-SETUP-CHROOT(8)				  Globus Toolkit			     GLOBUS-GRIDFTP-SERVER-SETUP-CHROOT(8)

NAME

       globus-gridftp-server-setup-chroot  -  creates  the  specific  contents of a directory that can specified as a root of the file system tree
       exposed by the Globus GridFTP server

SYNOPSYS

       globus-gridftp-server-setup-chroot [-c certificate_dir] -r chroot_path_to_create

DESCRIPTION

       GridFTP server can be configured to restrict access to specific path using the command line  option  -chroot-path  of  the  globus-gridftp-
       server command. The specified path will become the new root after authentication.

       That path must contain a valid certificate structure, and the files /etc/passwd and /etc/groups.

       The command globus-gridftp-server-setup-chroot helps creating such a suitable directory structure.

OPTIONS

       -r chroot_path_to_create
	      Creates  in  chroot_path_to_create the directory structure expected by the globus-gridftp-server command, when started with -chroot-
	      path command line option.

       -c certificate_dir
	      Specifies explicitly the directory from which the certificates will be copied into the directory chroot_path_to_create. The  default
	      path is /etc/grid-security/certificates.
