Oracle Error Message
ORA-07252: spcre: semget error, could not allocate semaphores.
Reason for the Error
Semget system call returned an error. Possible resource limit problem.
Solution
Check errno. Verify that enough semaphores are available in system. If additional errors occur in destroying the semaphore sets then sercose[0] will be non-zero. If this occurs, remove the semaphore sets using ipcrm.
