Just throwing a thought out there, but what about swap file access? <br>
It's a reach, but if there's a lot of swapping, even to SSD, maybe <br>
there's a clue?<br>
<br>
# swapon --show<br>

<br>
That *is* neat.<br>
<br>
I've got a Dell PowerEdge screaming like a 747 in a spare room and one <br>
CPU is about 10°C warmer than the other, all the time.<br>
<br>
I might just look into repasting it, that's really a good idea.<br>
<br>
<br>
Thanks!<br>
