1 to MAXINT
The amount of space that could possibly be consumed by the semaphores and their supporting data structures is compared to 25 percent of the kernel memory available at the time the module is first loaded. If the memory threshold is exceeded, the module refuses to load and the semaphore facility is not available.
When the default value is not enough. Generally changed at the recommendation of software vendors. No error messages are displayed when an attempt is made to perform more semaphore operations in a single semop call than are currently allowed. Instead, the application receives a return code of E2BIG from a semop() call.
