 Hello,
 some people might report that avast4linux/Workstation doesn't work with
 latest VPS (problem started with 100328-1 for them). The reason is that
 "macro"-block in 400.vps is now depacked to something bigger than
 33554432 bytes - this is an artificial SHM block limitation in some
 Linux kernels (kernel.shmmax).

 Solution? 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 (after boot).

 regards,
 Ondrej Bechyne
