Hi Florin, The good news is that this is not a kernel bug. The reason for the kernel messages is that the Ethernet driver tried to allocate some buffer space and the zoned buddy allocator could not find any free memory for this - so it dumped out a stack trace and a summary of memory subsystem to alert you of the fact.
Such reports occur when the zoned buddy allocator memory becomes heavily fragmented through use and a contiguous block of memory cannot be allocated, for example, allocation of large receive buffers for Ethernet Jumbo Frames. >From your log, the machine was only running for ~13 days, which isn't that long, so it's surprising that fragmentation occurred so quickly. This problem can be reduced or eliminated by changing the amount of available memory for receive buffer allocation, by increasing /proc/sys/vm/min_free_kbytes, as you have done. >From this point, I shall mark this as "Won't Fix" as it is not a kernel bug, but a kernel configuration tweak. ** Changed in: linux (Ubuntu) Status: In Progress => Won't Fix -- oops in Hardy Heron -server kernel, with md-lvm-xfs-nfs4 https://bugs.launchpad.net/bugs/198357 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
