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
