Reproduced multiple times on 10.04 On 10.04 this is also happening to us with a vm.min_free_kbytes set to 11140:
# sysctl vm.min_free_kbytes vm.min_free_kbytes = 11140 Running multiple (10+) 10.04 instances on EC2, and reproduced over 15 times, but most often resulting in hung/non-responsive servers rather than a recovery. It's fairly easy to reproduce this by increasing the MTU=9000 instead of default 1500, and moving large files, at which point it will hang the system or crash the system. I'm now increasing that to 32252 to see how we fare at that point. Would love to use jumbo frames as well, but causes crash within a few days (when we get high NFS load = network load) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/591947 Title: Copying large files to NFS mount blocks system -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
