Hi all. I run Gentoo linux, with mdev replacing udev. I occasionally run a script that does quite a bit of copying back and forth, and it uses /dev/shm to speed things up. Yesterday, it started blowing up on me. After painfull debugging, I discovered that /dev/shm is now only 10 megabytes. The default linux size is 50% of ram. Since I have 3 gigabytes, that should allow 1.5 gigabytes in /dev/shm. I haven't run this script for a while, so the change may have been a few months ago. Is there an option I can set somewhere to override this limit? I tried remounting and bindmounting it, without any effect.
Here is my /etc/mtab for diagnostics.
