FreeBSD 6 Hard Lock no logs

Hi,

I have a web/mail server thats running the lastest version of FreeBSD 
6.0-RELEASE-p9 #4. In the last month or so it's started hard locking..
when the machine locks up i can still ping it and get connects from 
telneting to 80,22,etc sometimes i get a banner and sometimes i dont.. 
but there are
no errors on the console or in the logs.

The odd thing is the locking seems to happen within a certain time 
window (mon,tues) and never end of the week or weekend.. i suspected it 
could have been
a bad cron job but nothing falls into that time frame.

As a test i've been rebooting the server everynight to see if that would 
help the machine get past the begining of the week with out a hang and 
again this morning
even though i rebooted last night at 10pm hung around 9:47am.

The machine is a Dell PowerEdge 2550, I've had dell come and replace the 
MB and have ran all their diagnostics aswell with no errors reported..
I've been reading alot about APIC and ACPI and people having similar 
issues but nothing that fits the bill... below is the dmesg and output 
of vmstat -i.. another odd thing is the rate for the CPU timer is 
extremely high compared to other machines with similar hardware or 
faster hardware.

Any help on where to look next would be awesome.
