I was surprised just now to see my CPU usage sitting at 100%. My connection is 10/1.4 mbps, so I'm used to seeing no more than about 15% under normal circumstances. Here's what top looks like at the moment and I'm not sure what to make of it.

Ok, so now apinger's not even on the list, but it was at the top when I started typing this. Any ideas?

There are some issues with apinger right now, so that isn't surprising. Last I heard it was going to be rewritten, but the guy rewriting it is off for a few days.

I'll just reboot for now then. What about some processes showing CPU usage of 73400% in top? I've never seen such a thing.

jimp

That's a bit odd, and usually only happens if there is a world/kernel mismatch. Is that still on the image from the 23rd?

clarknova

yes. I just rebooted it but I'm in no hurry to update it unless this starts happening a lot.

same problem here. I just rebooted this morning because the network was slow like hell.
I saw the same thing : apinger using more than 95% CPU !!!

is there any news about apinger for the issue ?

There have been quite a few updates since then on the builder systems. Update to today's snapshot and try again.
