Hi All

How can I free the shared memory and semaphore

I have done ipcrm -m shmid (98304) but still it is show 0x000000 98304

Then only option is to reboot ..Is there any way other than reboot

Thanks

Ok, so show us the output of 'ipcs' please, just so we can see a bit more of what's going on.

Are you sure the shared memory segment you're trying to free isn't in use?

just ensure that no process is using the shared memory.

to check for which process id is using the shared memory use 'ipcs -p' and ensure no process is using. if any process is using it, kill the process and then remove the shared memory by using ipcrm

Hope this helps,
Gopi

ipcs -p and killed the process
