For Solaris Zones:

In practical terms, Oracle requested a resource from the operating system (e.g., a shared memory segment or a semaphore set), and the OS replied: "I cannot give you that resource right now, try again later." Because Oracle cannot proceed without that resource, it aborts the operation and throws ORA-27103. SEMMSL = 250 (or max processes per instance)
