/dev/shm space in red hat linux

I am using redhat linux machine and oracle11g version.

/dev/shm shows 88%. Will this be freed automatically? OR should i clean any files?
>df -h

                      7.6G  2.2G  5.1G  30% /
                      1.9G   63M  1.8G   4% /home
                      1.9G  519M  1.3G  29% /var
/dev/cciss/c0d0p1     251M  156M   83M  66% /boot

fpmurphy, thanks for your response. I don't have any plan to shutdown at this moment. But does this impact anything now?

Currently there won't be any impact,However,when you try to start some other APP you may get a shm errors.

It also means you're out 11 gigs of RAM of course.
