[asterisk-users] Asterisk 1.62.13 - CPU spikes every 10 minutes - NOT FIXED

[Mike]

All Digium, on a HP DL360G5. I am using the TE420 (4 ports, PCIe) and a
TCE400B

If you are asking for cat /proc/interrupts (sorry, not much of a H/W guy)
that would be the answer:
           CPU0       CPU1       CPU2       CPU3
  0: 3692453723          0          0          0    IO-APIC-edge  timer

If, as a non-HW guy, I understand correctly, it means that each card is
sharing interrupts with a USB port.  Nothing is plugged in those USB ports.

If I remember correctly, the HP BIOS didn't let me do what I wanted exactly.
Would disabling the USB ports help?
