--- Begin Message ---Package: linux-2.6 Version: 2.6.26-22lenny1 Severity: normal Hi, I have noticed the following behaviour on a couple of our hosts running 2.6.26-2-amd64 inside a KVM instance with virtio network interfaces.

This *might* be the same bug as https://bugzilla.redhat.com/show_bug.cgi?id=520119 which was fixed upstream with this patch against 2.6.31: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=3161e453e4 Unfortunately, the 2.6.26 virtio code is significantly different and this patch does not apply as-is, however it seems to me that 2.6.26 doesn't appear to be checking for oom while allocating buffers as well.

--- Begin Message ---Hi, your bug has been filed against the "linux-2.6" source package and was filed for a kernel older than the recently released Debian 7.0 / Wheezy with a severity less than important. We don't have the ressources to reproduce the complete backlog of all older kernel bugs, so we're closing this bug for now. If you can reproduce the bug with Debian Wheezy or a more recent kernel from testing or unstable, please reopen the bug by sending a mail to cont...@bugs.debian.org with the following three commands included in the mail: reopen BUGNUMBER reassign BUGNUMBER src:linux thanks Cheers, Moritz
