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

[Mike]

Shaun,

Thanks for all the help.  I tried but couldn't see a definite spike anyways.
I used mpstat to see the irq% for each CPU, and although it shows me spikes
to 100% for one CPU (not always the same one is spiking irq%) the intr/s
isn't actually spiking.

It`s like suddently there aren't more interrupts, but the IRQ% time for the
CPU shoots up.

What can make it do that?

Mike
