Hi,

I've got a question....
If I get a shared memory segment and not remove before I terminate my program, the shared memory segment is gonna just sit there, right?
Then, does it ever get reclaimed by itself??

Thx.

Hi,

You need to clean it yourself with

ipcrm -m shmid

ipcs -m will list shared memory on your system

If You interested in automatic shm removal upon lasy process detach use
www.grsecurity.net or http://www.openwall.com/linux/ patch.
Otherwise it will sit there untill removed/rebooted. But note, that it will eventually be moved to swap, and therefore the physical ram will be freed.
