Is it kernel bug? The code works normally on ia64 machine,howerver, on
EM64T,it fails tot work.
The function call of shmat will change /proc/meminfo;and the shmdt
can't restore it to original content. How to restore it to original
stauts?Thanks.

Did you check ipc? Command 'ipcs -a" could show all shared memory. I guess you app doesn't call shmctl(..., IPC_RMID, ...) after shmdt. Use ipcrm to release them manually.
