Title: avast, /proc/sys/kernel/shmmax is insufficient for avast to run Status in “linux” package in Ubuntu: Fix Committed Bug description: Avast for linux requires a higher value in order to be able to update its signature database. This is the info they post on their forum to help people fix the issue: "Starting with the 400.vps, version 100328-1, one of it's internal block reached the inner limit 33554432 bytes. It's a kernel variable which is (quite artificially) limiting the maximum size of any SHM memory block - and 33554432 was a default for some kernels. 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 (just after boot)." The current value in Ubuntu 10.04 is: silviu@silviu-lucid:~$ cat /proc/sys/kernel/shmmax 33554432 Is there any reason to have this default and not something along the lines that the Avast staff suggest. Could future Ubuntu releases have "128000000" as default ? Would be nice if newbie switchers could just fire off their on demand scanner and have it work out of the box.
