One of our machines are being bitten by that bug, once every 2-4 weeks or so xenconsoled dies and all the VMs stop responding intil xenconsoled is restarted. I googled for it and I saw many people reporting it but no solution for it. Does anyone know if it is solved in 5.5? I can't upgrade the box (it's a production box) unless I can prove the problem will go away. thanks in advance

Hi. On my FreeBSD 4.8 configured IPFW2+IPF+IPNAT and I use them all: - IPFW - traffic accounting, shaping, balancing and filtering; - IPFilter - policy routing; - IPNAT - masquerading. I want to know, how IP-packets flow through all of this components? What's the path? incoming: IPFW Layer2 -> IPFW&Dummynet -> IPNAT -> IPFilter ? outgoing: IPFW Layer2 ->

I've had a few systems with a lot of RAM and very busy filesystems come up with filesystem errors that took a manual 'fsck -y' after what should have been a clean reboot. This is particularly annoying on remote systems where I have to talk someone else through the recovery. Is there some time limit on the cache write with a 'reboot' (no options) command or is ext4 that

Hi, I have samba-3.0.28a crosscompiled and running on a MIPS platform. The development system has about 150MB of free RAM after system bootup and no swap space. The system also has an USB interface, to which an external USB hard disk is connected. When I try to transfer huge files above (100MB) from a client on to the USB hard disk, I find that the page cache eats up almost about 100MB and

I have four NFS servers running on Dell hardware (PE2900) under CentOS 5.7, x86_64. The number of NFS clients is about 170. A few days ago, one of the four, with no apparent changes, stopped responding to NFS requests for two minutes every half an hour (approx). Let's call this "the hang". It has been doing this for four days now. There are no log messages of any kind pertaining

I believe 30 sec is the default for the checkpoint interval.  Is this adjustable? -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
