free"莫名"出现shared内存使用?没有tmpfs,ksm的run也是0,zram也关掉了
内核也没有打UKSM之类的补丁
如何分析shared非0的原因?
3.16和4.5内核都这样
但我想来想去没什么发现?
我进入桌面后立即打开lxterminal运行"watch -n 1 free -b"查看,结果还是有
而且这些shared内存的数值还在不断变化,并非静止不动
桌面环境是LXDE
难道是某些软件依赖了gnome的组件?
sudo killall gnome-pty-helper
根本没用
killall -s KILL gnome-pty-helper
可以杀死进程,但没有什么用,共享内存依旧...
