Ron,

   Run

      ipcs -s
  and check what you have. Sempaphores are usually used to synchronize processes - when a process holds the semaphore, any other process anted to hold it waits until it is released. Quite similar to an Oracle lock. It's possible that an instance crashed without releasing some resources. the trouble will be with identifying the semaphores that are here and shouldn't. Otherwise they can be deleted with ipcrm.
