I've been trying to diagnose why my server has a constant idle time of 90% even when nothing is running. After finally discovering what hi means in 'top' (it means hardware interrupts) I find that this percentage always averages around 7-10%. How can I find out what is causing this constant load of interrupts? I have a Dell 1850 3.0Ghz with on board RAID and 2GB RAM. Anyone else experiencing this? Do a ps ax |grep mpg and see if you have more then two mpg's running. If you do, stop asterisk, kill all remaining mpg's, and restart asterisk. ___ --Bandwidth and Colocation sponsored by Easynews.com -- Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Re: [Asterisk-Users] OT: Hardware Interrupts; Who is it?
OK. Perhaps I was not clear. Please read my original post again: I've been trying to diagnose why my server has a constant idle time of 90% even when nothing is running. I did not say 90% usage I said 90% idle. Meaning I have a constant CPU usage of 10%. This 10% measurement comes from the hardware interrupt (hi) from within top: Cpu(s): 3.8% us, 2.1% sy, 0.0% ni, 85.5% id, 0.2% wa, 8.0% hi, 0.4% si Even when all other percentages are at 0%, hi remains around 10%.

Re: [Asterisk-Users] OT: Hardware Interrupts; Who is it?
It means you have a piece of hardware that is generating a lot of interupts. Try a few commands like this: # vmstat 1 # watch -n1 cat /proc/interrupts Go through lspci -vb and disable hardware that's not being used. Watch the numbers as they increase.
