Interrupt spikes on 10 minute intervals is not (should not be) the norm
with DAHDI hardware.  What is the make/model of the PRI card that you
are using? Do you know what devices are on the interrupt line on which
you see the spike?

The TCE400 will generate many interrupts when channels are setup and
destroyed and will generate an interrupt for each packet to be
transcoded.  When you have more than 40 channels open the card will
switch off interrupts and just poll the interface.  So, given that, it's
possible that if the call load is dipping below 40 channels and then
going back over you could see an interrupt spike, but that doesn't sound
like what you're describing.
