Just as a follow-on to my comment in #58. It's unlikely I'll be able to test this as we've now migrated everything away to a different distribution, so unfortunately I won't get a chance to try any new kernels. -- High load averages on Lucid while idling https://bugs.launchpad.net/bugs/574910 Yo

I tried the aki-84b75ded kernel on an EC2 instance running our AMI and it locked up within 10 mins. There's nothing in the EC2 system log to indicate why, and the instance became completely unresponsive to outside world so I couldn't use an existing session to look at the system logs. -- High lo

Scott, thanks for the update. As always I appreciate an open an honest answer. I can understand you can't predict how long it will take to fix the bug, but similarly we can't tell how long customers will continue to use the degraded service that is the best we could offer under 10.04 LTS, hence th

Can we have an update to confirm that; a) It's been agreed it's not "simply an accounting/reporting problem.", and is something that impacts performance and b) Details of whats being done to fix it So people, like myself, who are waiting for this to be resolved in order to switch back to 10.04

Thanks for the update. The performance of the EC2 10.04 images is noticeably slower than the 8.04 LTS ones we were running, so I'm pretty sure it's not just a case of the load being incorrectly reported, hence why I've been actively monitoring this issue. Given what you've said it seems unlikely t

This is getting silly. I currently have 2 Amazon EC2 instances running 10.04 LTS, both of which sit at around 1.0 load and can go to 4, and that's only serving a few users. They were "upgraded" from 8.04 LTS where the load rarely went above 0.5. I'm guessing as this hasn't been resolved for nearly
