Linux high load no cpu

top shows high user-space CPU utilization but all the process show 0

Any ideas on why the load would be through the roof, top shows each CPU user-space utilization at 85% or higher, yet no process is tagged with any CPU utilization? First time I’ve ever seen this. We’ve got a server that has a load average of 20, and the break down on each CPU is extremely high (>85%), yet none of the processes in the list have any CPU % utilization. Here’s a sample, and yes, this is with the processes sorted from highest to lowest CPU utilization — every once in a blue moon we’ll actually see a process that shows «1» as the CPU %. This is a mysql server box.

High load average, low CPU usage — why?

The applications running on this server talk with an Oracle database on a different server.

This server has 32GB of RAM and 10 CPUs (I think).

Running prstat -Z gives something like this:

I understand that CPU is mostly idle, but the load average is high, which is quite strange to me. Memory doesn’t seem to be a problem.

Running vmstat 15 gives something like this:

I understand that the CPU is mostly idle, no processes are waiting in the queue to be executed, little swapping is happening.

14.04 High Load Average — but no CPU

I’ve got as system with 6 hperthreaded cores and 64Gb of RAM, just stood up 14.04 wit KVM, and I’m seeing load averages above 50, with only a VM install going on. NO high CPU, NO high I/O, just crazy load average. It also fluctuates all over. Any suggestions on where to look greatly appreciated Here’s top:
