Hello , Following message is causing our server to halt. Please, suggest.
I suspect something else is causing your problems.
"Feb 27 13:54:03 MWG kernel: [18464.328680] The scan_unevictable_pages sysctl/node-interface has been disabled for lack of a legitimate use case. If you have one, please send an email to linux-mm@xxxxxxxxx <mailto:linux-mm@xxxxxxxxx>."
Writing to /proc/sys/vm/scan_unevictable_pages causes that warning to be printed exactly once, after which the system should continue running the way it did before. As an aside, do you have a legitimate use case for scan_unevictable_pages? :) It would be good to get more information on what happens when your system is about to hang (or hanging). What version are you running? Do you see lots of unevictable pages? What about active/inactive anon/file pages? What about free memory? What about slab? Page tables? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx. For more info on Linux MM, see: http://www.linux-mm.org/ .
