Sounds likely. The standard utility programs ipcs and ipcrm will help you
clean up --- see their man pages. (You probably will need to zap the
old shared-memory segments as well as the old semaphores; these tools
will handle both tasks.)
Our distribution includes a shell script "ipcclean" that purports to
do this for you, but I wouldn't trust it too far, since the output
format of ipcs is somewhat platform-specific.
