So this fix is also in Maverick beta? Unfortunately then it does not seem to fix those problems I'm having.
I installed Maverick beta (2.6.35-19-server, amd64, clean installation) under kvm and was able to repro some of my earlier problems. I see this most often when using torretflux to download multiple large (1GB) files simultaneously and save them on a nfs-mounted folder. This is the easiest method to repro this in Lucid, and seems to trigger the case also in Maverick. I have had this problem also when using emusic.com emusicj (java) mp3 downloader and when renaming multiple image files with renrot (these methods I have tried only in Lucid). These all process files over nfs, but don't utilize CPU that much. I wrote some simple test scripts to try to repro this. First script uses dd to read and write several files simultaneously, but that hanged only once (syslog1 attached) even if I let it run for hours. Another script downloads simultaneously six 8MB files using wget, and that seemed to hang more easily. I run it twice, and both times it hanged (dmesg2, dmesg3). ** Attachment added: "logs.zip" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/561210/+attachment/1547059/+files/logs.zip -- Writing big files to NFS target causes system lock up https://bugs.launchpad.net/bugs/561210 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
