I'm running mdev, so that may be related.  Here's my story... a script
I run to automatically process digital photos started blowing up on me.
After much bashing of head against brick wall, I determined that
/dev/shm now has an absolute max size of 10 megabytes!  Any larger files
could not be written to it.  Here's all the uncommented stuff in /etc/fstab


/dev/sda5               /         ext2     noatime,nodiratime,async        0 1
/dev/sda7               /home     reiserfs noatime,nodiratime,async,notail 0 1
/home/bindmounts/opt    /opt      auto     bind                            0 0
/home/bindmounts/var    /var      auto     bind                            0 0
/home/bindmounts/usr    /usr      auto     bind                            0 0
/home/bindmounts/tmp    /tmp      auto     bind                            0 0
/dev/sda6               none            swap            sw              0 0
/dev/cdrom              /mnt/cdrom      iso9660         noauto,users,ro 0 0
/dev/sr0                /mnt/dvd        auto            noauto,users,ro  0 0
devpts  /dev/pts devpts defaults 0 0
none              /dev/shm        tmpfs rw,noatime,noexec,nosuid,nodev 0 0

  Meanwhile, my netbook, with the /dev/shm line commented out, runs just
fine and handles large files in /dev/shm.  I followed the example at
http://wiki.gentoo.org/wiki/Complete_Handbook/Configuring_the_system
with slightly more paranoid settings, e.g. noexec.  What gives?
