[Kernel-packages] [Bug 1319244] Re: iostat: Cannot open /proc/stat: Cannot allocate memory
It turns out we (you) were not the first ones running into it. The IBM mainframe guys (obviously) have the same need to potentially allow many CPUs. The upstream discussion is here: https://lkml.org/lkml/2014/5/21/251 So, while the change I made does work in this case, it can cause issues. Firstly /proc/stat uses a open_single interface. That means the proc file is not seekable and has no iterator. So all output has to be done in one go. And that means the buffer _has_ to be big enough to hold all output. Which means the part that limits the maximum size to order-3 allocations can cause issue on systems that really have a lot of CPUs. The other part of changing the buffer from holding x*possible number of CPUs to x*online CPUs was also thought of in the upstream thread. The problem there is that between open (buffer gets allocated) and show (buffer is filled) it is possible than a bunch of CPUs are set online. So one needs to be extra careful what would happen then. Sounds like the most likely outcome could be to have a vmalloc fallback option. But the discussion does not seem to be finished, yet. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1319244 Title: iostat: Cannot open /proc/stat: Cannot allocate memory Status in “linux” package in Ubuntu: Confirmed Bug description: Intermitently I get errors stating that various programs cannot allocate memory when reading /proc/stat I have 2 servers that are affected by the issue.

[Kernel-packages] [Bug 1319244] Re: iostat: Cannot open /proc/stat: Cannot allocate memory
It looks like two things at play: 1. Something in the way the system is set up seems to the DMA/DMA32 pool under higher pressure 2. Reading /proc/stat ends up requesting a 64kB memory area (order-4) in the DMA32 pool on node0 While there are still two elements in the 64kB slot, they both are emergency reserve, which open_stat did not ask for. So while there is not much that can easily be done about the memory pressure in general, it looks like open_stat could very well be more conservative about its memory requirement. First the calculation reserves 128 bytes for each possible cpu, while the actual output only produces one line of overall stats, plus one for each online cpu. So it seems to make sense to use the number of online cpus for the allocation. Second the upper limit for the buffer is set to the maximum that kmalloc can do. However it is known that anything beyond order-3 allocations (32kB) are costly and prone to fail due to memory pressure. And having a smaller buffer is not world ending for the stat output either. Since the proc file uses the seq_file functions it only would cause more read calls instead of filling all stats into one single buffer. ** Changed in: linux (Ubuntu) Importance: Undecided = Medium ** Changed in: linux (Ubuntu) Assignee: (unassigned) = Stefan Bader (smb) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1319244 Title: iostat: Cannot open /proc/stat: Cannot allocate memory Status in “linux” package in Ubuntu: Confirmed Bug description: Intermitently I get errors stating that various programs cannot allocate memory when reading /proc/stat I have 2 servers that are affected by the issue.
