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

[Mike]

(sorry for the series of email, I realize I seem to be having a discussion
with myself).

I was wrong, the "problem" isn't fixed.  Is having IRQ spikes every 10
minutes (under no load at all) the norm with Dahdi hardware?
