We have quite a lot of instrumentation for memory consumption - were you able to work out where it went by comparing /proc/meminfo, /proc/slabinfo, `echo m > /proc/sysrq-trigger', etc? Is the memory missing on initial boot up, or does it take some time for the problem to become evident? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
