ipc.c contains this code: if ((filebench_shm->shm_id = shmget(0, size, IPC_CREAT | 0666)) == -1) { filebench_log(LOG_ERROR, "Failed to create %zd bytes of ISM shared memory (ret = %d)", size, errno); return (-1); } Those 0666 permission flags should be 0600. I tried to create threads with the "useism" flag, but I couldn't reach this code. I noticed that the final example in the "filebench -h" output does not actually work because it contains a syntax error.
