解决办法是:终端执行:
sudo sysctl -w kernel.shmmax=128000000
然后,再打开Avast 杀毒,软件正常。
或者:
Set the limit to higher values (as root):
sysctl -w kernel.shmmax=128000000
OR
echo 128000000 >/proc/sys/kernel/shmmax
Place those lines to /etc/init.d/rcS or equivalent file (it's distribution-specific a bit - see /etc/inittab, the sysinit runlevel) to have them set automatically (just after boot).
