[Kernel-packages] [Bug 1319244] Re: iostat: Cannot open /proc/stat: Cannot allocate memory
Alright the test kernel clearly fixed the issue. My gut tells me that there might be some memory leak also at play with the non patched version, but I don't know kernel code well enough to analyze that. -- 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.
