this is what it looks like after your change. seems to be good now. $ ./strace -eipc ipcs shmctl(0, IPC_64|SHM_INFO, 0x11fba6f20) = 0 ------ Shared Memory Segments -------- key shmid owner perms bytes nattch status shmctl(0, IPC_64|SHM_STAT, 0x11fba6f98) = -1 EINVAL (Invalid argument) semctl(0, 0, IPC_64|SEM_INFO, 0x11fba6fa0) = 0 ------ Semaphore Arrays -------- key semid owner perms nsems semctl(0, 0, IPC_64|SEM_STAT, 0x11fba6fc8) = -1 EINVAL (Invalid argument) msgctl(0, IPC_64|MSG_INFO, 0x11fba6f80) = 0 ------ Message Queues -------- key msqid owner perms used-bytes messages msgctl(0, IPC_64|MSG_STAT, 0x11fba6fa0) = -1 EINVAL (Invalid argument) +++ exited with 0 +++ -mike
