central processing unit - High CPU load but top processes in top all around 0%




We have a server with unusual high load and cpu util, but we can't figure out why. When we run top all the procs seem to be very low cpu.

Is there a better way to look for what is causing this?


Answer



I think this bug is your case. From what I see from the output, you have enough memory (note the cached 14 GB or so), no I/O issues, but you have xen-related processes running. This make me think it is a bug.
