[Bug 708920] Re: Strange 'fork/clone' blocking behavior under high cpu usage on EC2
Hi Stefan, Just an update. That same node has run flawlessly under high load since my last post, no lockups. What are your thoughts on the claim that this bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/727459 is the cause of the problem?

[Bug 708920] Re: Strange 'fork/clone' blocking behavior under high cpu usage on EC2
Stefan, I've been testing your kernels and stability seems much improved. It's only been a few days but the server has been under quite a lot of load without an issue, with the stock ec2 kernel this was definitely not the case. Cautious optimism, but I'd love to isolate which of the patches was the fix. do you have a list of the patches you incorporated? -- You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. https://bugs.launchpad.net/bugs/708920 Title: Strange 'fork/clone' blocking behavior under high cpu usage on EC2 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
