shared memory not removing properly.
Hi all,
I am using some geophysics applications and the data volumes are too high. sometimes my system used hang and i used to kill the X session. while i respawn the application, and while loading the data it used to say that the project was still in use. In IRIX if i fire the "ipcs -a" command it will list the shared memory objects. I can remove by "ipcrm -m shmemid". But in RHEL 5, these commands are working but its not getting removed from memory. If i fire the "ipcs -a" command, again it shows the same shared memory id and size of the project. How to flush these shared memory things from system?. my system has 64 GB RAM, 102 GB swap space and Intel Xeon X5450 @ 3.00 GHz KingstoN |
probably it's because you didn't killed a process that was actually using that data. so while it's still there data may not be available.

i killed all the processes first...then only i tried with ipcrm command
but still problem persists... |

Are you sure that all processes that uses shared memory killed ? Did ipcrm give any error message ? |
sure...i killed all the processes. ipcrm too didnt give any error message. the moment when i give "ipcrm -m 68686868". immediately i got the prompt. But if i check with "ipcs -a" command, the same process with the id is still there.
