Description of problem: Mounting and umounting a partition frequently(e.g., autofs) will decrease the LowFree of memory, and it won't go up. When the value of LowFree is very small, oom-killer will be triggered, and then other progresses will be killed. Version-Release number of selected component (if applicable): mount (util-linux 2.13-pre7) How reproducible: 100% Steps to Reproduce: 1. watch 'cat /proc/meminfo | grep LowFree' 2. I use default timeout(5min) of autofs, it will be reproduced in 51 days. I tried the way below, and it will reproduced in several hours. while [ true ]; do mount /dev/sdb1 /mnt umount /mnt done Actual results: Lowfree reduced to 8M, other progresses are killed by oom-killer. Expected results: Lowfree decreased while mounting,but it should go up after umounting. Additional info:
