similar to: Dom0 OOM, page allocation failure

I have continous oom&panic situation unresolved. I am not sure system fills up all the ram (36GB). Why this system triggered this oom situation? Is it about some other memory? highmem? lowmem? stack size?

Not sure if it''s anything interesting - I had the following entry in dmesg a few days ago, on a server with 32 GB RAM. The system is still working fine.

Dear list, I am seeing an error across multiple machines during heavy I/O, either disk or network. The VMs are on different Intel CPUs (Core 2 Quad, Core i5, Xeon) with varying boards (Abit, Asus, Supermicro). Machines that get this error are running either BackupPC, Zabbix (MySQL) or SABNZBd. I can also reproduce the error on the Supermicros with a looped wget of an ubuntu ISO as they are

hi xen 4.0.1 w/2.6.32.41 Last week dom0 experienced an hard crash and box need to be restarted manually (despite kernel.panic=20). Serial console was not setup, only netconsole. No relevant entries through netconsole, but analyzing logs I see some crashes twenty minutes before fatal hang.

Hi Wei, I ran into the following problem when trying to boot another guest after less than a day of uptime. (the system started 15 guests at boot already which went fine). dom0 is allocated a fixed 1536M. Both host as pv guests run the same kernel, some hvm''s run a slightly older kernel (3.9 f.e.) The are quite some granttable messages in xl dmesg, i also included these and a

Hi All, Running into temporary pauses in our VMs which correspond to these errors in dmesg on the dom0: [1721485.352560] SLUB: Unable to allocate memory on node -1 (gfp=0x20) [1721485.352563] cache: kmalloc-2048, object size: 2048, buffer size: 2048, default order: 3, min order: 0 [1721485.352566] node 0: slabs: 81, objs: 1296, free: 0 [1721485.352576] swapper: page allocation failure:

Hi Konrad, In one of my domU''s to which I pci passthrough USB cards with a videograbber connected to it, the videocapture bails out after running for quite some time with the stacktrace below. I guess i''m interpreting the mem-info below wrong, but i fail to see why it can''t allocate those 185088 bytes. Could you shed some light ? it''s probably the coherent

Package: xen-hypervisor-4.1-amd64 Version: 4.1.4-3+deb7u1 Severity: normal I tried GRUB_CMDLINE_XEN="dom0_mem=8192M": that delivers 6964868K total, then crashes when used=2837436K free=4127432K. By crash I mean the gnome screen was blown away, replaced by a black screen with white log lines. That seems to happen every time dom0 uses a large amount of memory. After setting

Hello On my HP Compaq dc5800 with Ubuntu 13.04 and their 3.8.0-19-lowlatency kernel, I''ve got quite some kernel traces in the syslog. You can find them below or at http://pastebin.com/bLXPBX67 (to avoid line breaks…). These kernel traces all begin with: WARNING: at fs/btrfs/free-space-cache.c:921 __btrfs_write_out_cache+0x6b9/0x9a0 [btrfs]() Most of the time, it starts with: Call

My web & name server runs out of memory from time to time, to the point where it's completely unresponsive to anything. At that point reset is the only alternative. (Or, as this is a virtual guest, I just say "virsh destroy"). But why this happens - I would like to know. The host in question is a KVM guest, and runs CentOS 6.4. From "top" (situation now): Mem:

I've been experiencing delays access data off my file server since I upgraded to 5.3... either I hosed something, have bad hardware or very unlikely, found a bug. When reading or writing data, the stream to the hdd's stops every 5-10 min and %iowait goes through the roof. I checked the logs and they are filled with this diagnostic data that I can't readily decipher. my setup

Hi I have a Dell PE2300 with a Digium TDM400P line card in it (with one module to handle an inbound phone line). This is running on a Fedora 8 system with Asterisk 1.4.21.2-1.fc8 This system has been working nicely for about 12 months. After a recent move of office and relocation of the server Asterisk is back on line, but the TDM line card has stopped working. I have spent half a day

I think you want kernel 4.10, or cherry-pick upstream commit 7dfee6827780d4228148263545af936d0cae8930.

I found that I''m able to provoke undefined behaviour with 2.6.38 with extent defragmenting + recompression, eg: mkfs.btrfs /dev/sdb mount /dev/sdb /mnt cp -xa / /mnt find /mnt -print0 | xargs -0 btrfs filesystem defragment -vc After a short time, I was seeing what looked like a secondary effect [1]. Reproducing with lock instrumentation reported recursive spinlock acquisition, probably

+cc: ocfs2-devel, sunil Marek, Thanks for the detailed report! Can I trouble you to file a bug at http://oss.oracle.com/bugzilla ... oh, is that your report http://oss.oracle.com/bugzilla/show_bug.cgi?id=1339? This looks like a deadlock of some sort. I don't think your hardware configuration really matters here. We'll keep looking into it. Joel On Tue, Dec 20, 2011 at 08:22:48AM

Hi, I am changing from proprietary nvidia drivers to Nouveau drivers in my mediacenter. I run a Gentoo linux in this hardware and I am facing an out of signal screen just after the boot (when the nouveau module is loaded). If I blacklist this module and modprobe it in the prompt, the screen gets out of signal in my 1080p TV in this moment. I tried recompile the kernel enabling and disabling a
