As Kevin Krieser suggested, you can run "ipcs -m -i <ID>" or check /proc/sysvipc/shm. There's cpid (creator's pid) and nattch (how many processes attaching to each segment). If the creator still exists, you can find it in ps output. If not, there's really no way I know of to find it. Perhaps you can schedule a cron job to frequently check the cpid in ps output in the middle of the day.
If nattch is 0, a shared memory segment is not cleaned up properly and most likely you can safely remove it by ipcrm.
